Diseases and Conditions

I had lived in this apartment for 5 years with no problems. Suddenly I started having terrible problems sleeping. I tried everything I could think of and finally went to my doctor who gave me sleeping pills. For over a year I needed a pill every night, sometimes a half worked, but only for a few hours and soon I would be using the second half. On Thursday, 4 days ago, newer and stronger meters we put in to replace the ones installed a little over a year ago. Now I cannot sleep, even with the sleeping pill and I am feeling so fatigued and muddle-brained that I can barely think straight and even have trouble standing up straight. I have literally done nothing since they have been put in and feel achy all over and disoriented, slightly dizzy.


Displayed background gamma radiation level is 9. Radioactive material is found throughout nature. Detectable amounts occur naturally in soil , rocks, water, air, and vegetation, from which it is inhaled and ingested into the body. In addition to this internal exposure, humans also receive external exposure from radioactive materials that remain outside the body and from cosmic radiation from space.

The worldwide average natural dose to humans is about 2. In some rich countries, like the US and Japan, artificial exposure is, on average, greater than the natural exposure, due to greater access to medical imaging.

As radiation exposure around the Fukushima nuclear power plant reach levels of mSv per hour (although they’ve since gone down), we thought it was time to put the figures into perspective.

Click here to read the Article Summary Where would you be without your microwave oven? You can cook a meal in seconds. Even frozen food can be defrosted and ready to eat in a matter of minutes. But have you ever wondered… are microwaves safe? Are there any dangers to using them? How could there be any dangers? If there were, the government would have taken microwave ovens off the market, right? These microwaves, which are a form of electromagnetic field EMF generated by a magnetron, vibrate at a speed of 2.

This causes the water molecules in the food to resonate at very high frequencies and generate heat. Conventional heating of food is a different, much more gentler process altogether. Heat is transferred by convection from the outside to the inside. Cooking with microwaves begins in the cells and molecules where water is present.

The Proven Dangers of Microwaves Is it possible that millions of people are ignorantly sacrificing their health in exchange for the convenience of microwave ovens? Why did the Soviet Union ban the use of microwave ovens in ? Who invented microwave ovens, and why? The answers to these questions may shock you into throwing your microwave oven in the trash. Because microwave ovens are so convenient and energy efficient, as compared to conventional ovens, very few homes or restaurants are without them.

In general, people believe that whatever a microwave oven does to foods cooked in it doesn’t have any negative effect on either the food or them.

Case Study #1: Lisa 8 “Early Menopause”, or Smart Meter Radiation? At 42 years old, Lisa is a single mom who does her best to stay healthy while juggling with her family and career.

It helps saves lives and provides great benefits to mankind in innumerable ways. Radiation is no different than other tools. If used improperly it can be hazardous to health or cause injury. But, if proper precautions are followed radiation can be used safely to achieve superior results. We will briefly introduce some basic radiation safety concepts and principles as they apply to the use of portable nuclear gauges.

While the human body can sense and take actions to prevent injury by many physical agents, such as heat and noise, it cannot sense radiation. Therefore, it is important to understand the nature of radiation, its sources, and how to protect yourself and others. A Brief History In , a German physicist named Wilhelm Roentgen fortuitously discovered X-rays while experimenting with evacuated glass tubes through which an electric current was passed. Roentgen discovered he could take a picture of the bones in his hand with the mysterious new rays.

Henri Becquerel of France discovered natural radioactivity a year later. In , Pierre and Marie Curie isolated the first radioactive elements, radium and polonium The momentous discoveries of these physicists led to a rapid advancement of scientific knowledge about radiation and radioactivity, as well as to many practical uses. Types of Radiation For purposes of radiation safety, only radiation with the capability to cause ionization is of concern.

These effects may take the form of damage to or disruption of the functioning of the internal organs and systems of the human organism or of changes in its functioning. Schwan was a German scientist who came to the US under a military ‘recruitment program’ after the war. He has worked at the University of Pennsylvania on numerous government contracts and set the first health and safety standards for electromagnetic radiation, adopted by the US government.

In Physical Properties of Biological Matter: Rajewsky and I had published a paper on the conductivity of erythrocytes, reporting, for the first time, dielectric measurements on biological materials extending up to 1, MHz.

I have been a cynical towards people who worry about smart meters for a couple years, even was an early adopter nearly 5 years ago. The last year I have been experiencing a chronic sore throat that my doctors can’t explain, my kids are developing learning disabilities, among other strange health issues.

Different types of electromagnetic radiation The total absorption coefficient of lead atomic number 82 for gamma rays, plotted versus gamma energy, and the contributions by the three effects. Here, the photoelectric effect dominates at low energy. Above 5 MeV, pair production starts to dominate. Even though photons are electrically neutral, they can ionize atoms directly through the photoelectric effect and the Compton effect. Either of those interactions will cause the ejection of an electron from an atom at relativistic speeds, turning that electron into a beta particle secondary beta particle that will ionize many other atoms.

Since most of the affected atoms are ionized directly by the secondary beta particles, photons are called indirectly ionizing radiation. It is otherwise called x-rays if produced outside the nucleus. The generic term photon is therefore used to describe both. Modern technologies and discoveries have resulted in an overlap between X-ray and gamma energies.

A sign pointing towards the Maralinga test site in South Australia in Peter Solness He also sought compensation for skin cancers, impotence, high cholesterol, arthritis, lung scarring, muscle cramps, mouth ulcers, tinnitus, skeletal hyperostosis and an overactive immune system. Comcare denied liability in despite accepting he suffered from the illnesses. Mr Elborough unsuccessfully challenged the decision at the Administrative Appeals Tribunal of Australia.

Bryan Charlton Maralinga, about kilometres north-west of Adelaide, was contaminated with radioactive waste in the s and early s after testing of fission bombs, including one dropped from an aircraft.

For exposure age dating (dating the time since the rock was exposed), the age range for cosmogenic nuclide dating therefore depends on the mineral chosen for analysis[1]. Beryillium and Aluminium (10 Be, 26 Al) are used most often because they are formed .

Nausea, vomiting, and diarrhea, lasting from a few minutes to several days Latent stage: Symptoms seem to disappear, and the person appears to recover Overt stage: Depending on the type of exposure, this can involve problems with the cardiovascular, gastrointestinal, hematopoietic, and central nervous system CNS Recovery or death: There may be a slow recovery, or the poisoning will be fatal.

Hematopoietic stem cells , or bone marrow cells, are the cells that all other blood cells derive from. Different doses, different effects The risk of illness depends on the dose. Very low doses of radiation are all around us all the time, and they do not have any effect. It also depends on the area of the body that is exposed. If the whole body is exposed to, say, 1, rads within a short time, this could be fatal.

However, far higher doses can be applied to a small area of the body with less risk. After a mild dose, the person may experience symptoms for just a few hours or days. However, a repeated or even a single, relatively low dose that produces few or no visible symptoms around the time of exposure may cause problems later on. A person who is exposed to 3, rads will experience nausea and vomiting, and they may experience confusion and a loss of consciousness within a few hours.

Tremors and convulsions will occur 5 to 6 hours after exposure.

Radiation exposure: a quick guide to what each level means

Safety standards were last updated in All around the world, countries are taking action to protect their citizens especially children against these abusive levels of EMF pollution. The French, German and Spanish governments have even issued recommendations to ban wifi from schools because of the developmental problems it could potentially cause in children. But is it really? Look — 25 years ago no one wore a seatbelt, because we had not yet uncovered the life-saving capacity of something as simple as securing yourself in a deadly moving vehicle.

Just like there are safe ways to ride in a car with your seatbelt securely fastened, there are safe ways to use modern technology like cell phones and wifi — without zapping your health.

As radiation exposure around the Fukushima nuclear power plant reach levels of mSv per hour (although they’ve since gone down), we thought it was time to put the figures into perspective.

His exposure of his anger shocked the company. The popular story explaining the origin of this expression is that the keeper of a general store used to nail counterfeit coins to the counter to discourage future customers from trying to perpetrate the same fraud. Blow the gaff is the British slang equivalent of spill the beans. Frederick Marry at, Peter Simple, blow the whistle To expose or threaten to expose a scandal; to put a stop to, put the kibosh on; to inform or squeal.

According to legend, the cackling of the sacred geese alerted the Roman garrison when the Gauls were attacking the Capitol, enabling them to save the city. Freudian slip A slip of the tongue; a seemingly innocent statement which has a concealed psychological significance. This expression comes from the psychoanalytical theories of Sigmund Freud, some of which hold that a person often reveals his true psyche in less than obvious ways, such as through slips in speech or through forgetfulness.

In its contemporary usage, however, Freudian slip has been carried to extremes and is often used to call attention to any slip of the tongue, especially if such attention might be embarrassing in a questionably humorous sort of way to the speaker. It was an odd little slip of the tongue … They call them Freudian slips nowadays.

What Are X-Rays? And How Does Radiography Work?

Blog home Radiation exposure: But how much radiation is too much – and what are we all exposed to? Click image for graphic As radiation exposure around the Fukushima nuclear power plant reach levels of mSv per hour although they’ve since gone down , we thought it was time to put the figures into perspective.

Human sources of radiation released into the atmosphere over the past 60 years, although serious, pale in comparison to the radionuclides already naturally present in the ocean.

Non-medical applications of X-rays Basics of electromagnetic force and radiation One of the four fundamental forces in nature along with gravity, weak nuclear force, and strong nuclear force , electromagnetic force was discovered in the s when scientists realized that electricity and magnetism were not two separate forces, but instead were the result of the same underlying force.

Force is essentially a pull or push on something by something else. In an interaction where I punch a boxing bag, I am imparting a force on that bag and probably hurting myself in the process. But force can be imparted without anything touching at all. Gravitational force between celestial bodies compels our planet to orbit the sun and compels the moon to orbit us.

And magnets exert force without touching as well. Within an atom, there are positively charged particles protons and negatively charged particles electrons , as well as neutral particles neutrons. Neutrons and protons are found within the nucleus of the atom, which is why they are called nucleons.

Seaborne Fukushima Radiation Plume Hits West Coast — How the Media Reported it Dangerously Wrong

Share this article Share The researchers took 20 ash trees and exposed them to various kinds of radiation for three months. The trees were exposed to six sources of radiation with frequencies ranging from to MHz and a power of mW at a distance of just 20 inches. This would eventually result in the death of parts of the leaves, the study found. Researchers also discovered that Wi-Fi radiation could slow the growth of corn cobs.

In the Netherlands, about 70 per cent of all trees in urban areas show the same symptoms, compared with only 10 per cent five years ago, the study found.

The power to manipulate radioactive decay and radiation spectra. Sub-power of Electromagnetism Manipulation, Weak Force Manipulation, Nuclear Manipulation and Solar Manipulation. User can create, shape and manipulate radioactivity, the process by which a nucleus of an unstable atom loses energy.

Earth is constantly bombarded with primary cosmic rays , high energy charged particles — mostly protons and alpha particles. These particles interact with atoms in atmospheric gases, producing a cascade of secondary particles that may in turn interact and reduce their energies in many reactions as they pass through the atmosphere.

By the time the cosmic ray cascade reaches the surface of Earth it is primarily composed of neutrons. In rock and other materials of similar density, most of the cosmic ray flux is absorbed within the first meter of exposed material in reactions that produce new isotopes called cosmogenic nuclides. At Earth’s surface most of these nuclides are produced by neutron spallation.

Using certain cosmogenic radionuclides , scientists can date how long a particular surface has been exposed, how long a certain piece of material has been buried, or how quickly a location or drainage basin is eroding. The cumulative flux of cosmic rays at a particular location can be affected by several factors, including elevation, geomagnetic latitude, the varying intensity of the Earth’s magnetic field , solar winds, and atmospheric shielding due to air pressure variations.

Rates of nuclide production must be estimated in order to date a rock sample. These rates are usually estimated empirically by comparing the concentration of nuclides produced in samples whose ages have been dated by other means, such as radiocarbon dating , thermoluminescence , or optically stimulated luminescence.

The excess relative to natural abundance of cosmogenic nuclides in a rock sample is usually measured by means of accelerator mass spectrometry. Cosmogenic nuclides such as these are produced by chains of spallation reactions. The production rate for a particular nuclide is a function of geomagnetic latitude, the amount of sky that can be seen from the point that is sampled, elevation, sample depth, and density of the material in which the sample is embedded.
