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 a person receives vary greatly?
because its radiation and it spreads far and and it is very poisinous and you could die of it
What is a safe amount of radiation?
Depends on the TYPE of radiation, how long you are exposed and the person being exposed. In the case of ionizing (nuclear) radiation, pregnant women and children have a lower safe level than other persons. For non-pregnant adults, 5,000 millirems per year is the maximum legal occupational exposure. However, the goal is always ALARA- a dose As Low As (is) Reasonably Achievable- meaning you do not expose a person for no reason. Other radiation- such as radio wave energy- has different levels. There is NO "safe" level that does not entail some risk of injury- just levels that are not found to be especially injurious.
What is nuclear transmission?
Nuclear transmission is that measurement of amount of radiation found inside of a shield versus the outside. The transmission is the amount of radiation that is received by passing through the protective shield.

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
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

Do granite counter tops give off radiation?
Granite does not give off radiation, though it may contain trace amounts of material which does. Any amount of radiation it releases should be insignificant (i.e. background radiation).
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.

18) The amount of radiation that an individual absorbs depends on?
On the amount of radiation emitted; on how close the individual is to the source of the radiation; on any objects in between which might absorb part of the radiation.
