Soviet bloc countries reported that individuals exposed to microwaves frequently developed headaches, fatigue, loss of appetite, sleepiness, difficulty in concentration, poor memory, emotional instability, and labile cardiovascular function, and established stringent exposure standards.
Describes the health effects on six men exposed to high levels of RF radiation (100 MHz) while working on transmission masts. Symptoms included headache, paresthesia, diarrhea, malaise and lassitude. The condition of the four men with the highest exposure has shown no significant improvement.
Symptoms of radiation sickness may include: Weakness, fatigue, fainting, confusion. Bleeding from the nose, mouth, gums, and rectum. Bruising, skin burns, open sores on the skin, sloughing of skin.
Brief exposure of a major part of the body to more than 1 Sv may cause acute radiation syndrome, which is characterized by (1) an initial prodromal stage of malaise, anorexia, nausea, and vomiting; (2) an ensuing latent period; (3) a second (main) phase of illness; and (4) either recovery or death (see Table 19-3).
Microwave sickness (MWS) has been a disputed condition. The syndrome involves the nervous system and includes fatigue, headaches, dysaesthesia and various autonomic effects in radiofrequency radiation workers.
But people who believe they're sensitive to EMFs report symptoms such as headache, fatigue, numbness or tingling, dizziness, trouble concentrating, insomnia, and memory loss.
The damaging effects of MW radiation on the brain include brain dysfunction and brain structural damage. An epidemiological survey found that MW radiation caused human fatigue, headache, excitement, dreams, memory loss and other symptoms of neurasthenia [20].
Prussian blue (Radiogardase).
This type of dye binds to particles of radioactive elements known as cesium and thallium. The radioactive particles then pass out of the body in feces. This treatment speeds up the elimination of the radioactive particles and reduces the amount of radiation cells may absorb.
Onset occurs 1 hour to 2 days after exposure. Stage lasts for minutes to days. Stem cells in bone marrow are dying, although patient may appear and feel well. Stage lasts 1 to 6 weeks.
Early symptoms of ARS typically include nausea, vomiting, headaches, fatigue, fever, and a short period of skin reddening. These symptoms may occur at radiation doses as low as 0.35 grays (35 rad). These symptoms are common to many illnesses, and may not, by themselves, indicate acute radiation sickness.
Why do people over 40 not need to take an iodine tablet in case of a radiation emergency? No link has been found between exposure to radioactive iodine and thyroid cancer in adults. This is why the World Health Organisation (WHO) does not recommend iodine tablets for people over 40 years of age in emergency situations.
What material stops each type of radiation? Paper, skin, or even a few centimeters of air can block alpha particles, and plastic, glass, or a few millimeters of aluminum can block beta particles. Lead, concrete, or several centimeters of dense material can block gamma rays and X-rays.
Domestic microwaves have been used since the mid 1950's. Since that time there has been no credible evidence to suggest they are in any way harmful to human health in normal use. The risk of injury from microwave radiation is effectively non-existent.
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.
The most common and widely recognized symbol for microwave safety is a trio of wavy lines stacked neatly on top of each other.
Two visible, potential signs of radiation sickness are nausea and vomiting. Since shock or pain can also cause nausea and vomiting, they are not necessarily an indication of radiation sickness. The symptoms must be weighed against the dose received to determine whether they indicate radiation sickness.
So, how long does radiation stay in the body after treatment? It depends on the type of therapy. People with chronic exposure to gamma rays and similar therapies (like the technicians who operate X-ray machines) may retain radiation for weeks or months. This depends heavily on whether or not they wear protective gear.
This series of disorders in organs is called acute radiation syndrome, which typically follows a course from the prodromal phase to the incubation phase, the onset phase, and finally to the convalescent phase or to death in the worst case.
Radiation shielding materials are various mixtures of elements that block scatter radiation. The most traditionally used element is lead (Pb). In addition to lead, other elements, such as tungsten, and titanium, have begun being used to create wearable equipment that protects against scatter radiation.
The most common symptoms are sensation of warmth potentially escalating to pain, profuse sweating, and skin burns if the exposure dose is sufficiently high. Life-threatening medical emergencies, permanent injury to the eye and visual system are less common.
Once inside shelter, remove your outer layer of clothing to remove contamination and radiation materials from your body. Take a shower or wash with soap and water to remove contamination from any skin or hair that was not covered.
Soviet bloc countries reported that individuals exposed to microwaves frequently developed headaches, fatigue, loss of appetite, sleepiness, difficulty in concentration, poor memory, emotional instability, and labile cardiovascular function, and established stringent exposure standards.
Microwaves are non-ionizing radiation, so they do not have the same risks as x-rays or other types of ionizing radiation. But, microwave radiation can heat body tissues the same way it heats food. Exposure to high levels of microwaves can cause skin burns or cataracts.
Microwave radiation leaks are hard to detect because you can't smell or see microwaves. The U.S. Food and Drug Administration (FDA), which regulates radiation-emitting products such as microwave ovens, advises against standing directly in front of or up against the oven while it is operating.
