What is the maximum amount of radiation a human body can tolerate?
100 milliSieverts is the smallest radiation dose clearly linked to cancer. 1 Sievert is the smallest radiation dose required to induce radiation sickness. The average person absorbs 250 millirems over a lifetime.
What is the average exposure of people living in the US to environmental background radiation?
The average worldwide exposure of people to environmental background radiation is about 2.4 mSv (milliSievert) per year. The referenced source does not break that down by country.Ref: "Report of the United Nations Scientific Committee on the Effects of Atomic Radiation to the General Assembly", http://www.unscear.org/docs/reports/gareport.pdf
Why does the amount of background radiation vary from place to place?
Background radiation levels vary from place to place due to factors such as altitude, geology, and proximity to radioactive materials like uranium and radon gas. Natural sources like cosmic rays and radioactive isotopes in the Earth's crust contribute to background radiation levels, which can fluctuate depending on these environmental factors.
Why does the amount of background radiation a person receives vary greatly?
The amount of background radiation a person receives can vary greatly due to factors such as geographical location (altitude and proximity to radioactive sources), lifestyle choices (smoking, diet), medical procedures (X-rays, CT scans), and occupational exposure (working in nuclear plants or flying frequently at high altitudes). These factors contribute to the variation in background radiation exposure among individuals.
Should people be worried about the amount of background radiation from nuclear power?
In general, the amount of background radiation from nuclear power plants is very low and well within safe limits set by regulatory authorities. Regular monitoring and strict safety measures are in place to minimize any potential risks to public health. However, it is still important for people to stay informed and aware of radiation safety practices.
How much millirems dose it take to be lethal?
About 100,000 millirems in a short amount of time is enough to kill you, but the variable in that is the "short amount of time" part
How much nuclear radiation is considered safe for humans?
From MIT: Adult: 5,000 Millirems per year The current federal occupational limit of exposure per year for an adult (the limit for a worker using radiation) is "as low as reasonably achievable; however, not to exceed 5,000 millirems" above the 300+ millirems of natural sources of radiation and any medical radiation. Radiation workers wear badges made of photographic film which indicate the exposure to radiation. Readings typically are taken monthly. A federal advisory committee recommends that the lifetime exposure be limited to a person's age multiplied by 1,000 millirems (example: for a 65-year-old person, 65,000 millirems). Minor: 500 Millirems The maximum permissible exposure for a person under 18 working with radiation is one-tenth the adult limit or not to exceed 500 millirems per year above the 300+ millirems of natural sources, plus medical radiation. This was established in 1957 and reviewed as recently as 1990. Fetus: 500 Millirems Or 50 Per Month (New Rule Jan. 1, 1994) New federal regulations went into effect New Year's Day, establishing for the first time an exposure limit for the embryo or fetus of a pregnant woman exposed to radiation at work. The limit for the gestation period is 500 millirems, with a recommendation that the exposure of a fetus be no more than 50 millirems per month. Weight Variables Like alcohol intoxication levels, levels of exposure to radioactivity (due to radioactivity deposited in the body) depend on a person's weight. A diagnostic tracer of one microcurie of radioactive calcium 45, given orally, would result in an exposure of 3.7 millirems for a 100-pound person, and half of that, 1.85 millirems, for a 200-pound person. Therapeutic Radiation Therapeutic radiation treatment that is delivered by administering radioactive material via the mouth or by injection usually results in high, very localized doses to a small part of the body, which absorbs most of the radioactivity. The radioactivity concentrates and remains in the target organ (for example, the thyroid) for a longer period of time than does the radioactivity that is distributed to the rest of the body. The radiation exposure for other parts of the body is a function of the amount of radioactivity per pound and the time the radioactivity is present in the tissue. As well if you are looking for ways to reduce your risk of radiation there are certain foods and supplements that you can take that can greatly reduce your risk, squidoo.com/radiation-alert-inspector-measure has more answers
Radiation measured in emissions is called what?
Radiation measured in emissions is referred to as radioactivity, specifically in terms of the amount of ionizing radiation emitted by a radioactive source. This is usually measured in units such as becquerels (Bq) or curies (Ci), which indicate the rate of radioactive decay.
What is the maximum amount of radiation a human body can tolerate?
100 milliSieverts is the smallest radiation dose clearly linked to cancer. 1 Sievert is the smallest radiation dose required to induce radiation sickness. The average person absorbs 250 millirems over a lifetime.
What is the current residual radiation of hiroshima and nagasaki?
Today, the background radiation in Hiroshima and Nagasaki is the same as the average amount of natural radiation present anywhere on Earth. It is not enough to affect human health. http://www.pcf.city.hiroshima.jp/kids/KPSH_E/question_box/question12.html

How do you convert mrads to mrems?
A rad measures the amount of radiation absorbed by a gram of material where as a rem measures the biological effects of different kinds of radiation. To measure the degree of biological effects produced by radiation you would need to know the mrad value as well as the type of radiation because different types of radiation produce different degrees of damage. For example every 1 mrad of beta or gamma radiation produces 1 mrem, every 1 mrad of high energy protons and neurons produce 10 mrems and every 1 mrad of alpha particles produce 20 mrems.

Why do you ignore background radiation?
For heat transfer: Background radiation can be dismiss in many case where the main radiation source is lot more stronger and result from including of background radiation to equation give complicate hardship with very infinitesimal result. For matter of health and safety: Harmful radiation would mean those of shorter than 250 nm wavelength or so. Background radiation from any ambient temperature or man-made heat source would yield very very tiny amount of those. Some minor radioactive decay do presence in every day life including our body that contain minor amount of radioactive carbon. For matter of Cellphone Microwave hoax: You will find plenty of these nuisance E-mail warning about danger of modern hi-tech equipment emitting microwave and radio frequency that cook the egg and pop the popcorn. Most of those old background radiation hoax was debunk but new creative method of public nuisance is always on the inbox.
