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.

Radioactivity is a part of our earth – it has existed all along. Fallout from nuclear explosives testing, and small quantities of radioactive materials released to the environment from coal and nuclear power plants, are also sources of radiation exposure to man.

This is because in addition to visible light the sun is also emitting radiation from all areas of the electromagnetic spectrum from radio waves to gamma rays. The higher end of this spectrum (X-ray to gamma) is dangerous radiation to human health.

Gamma rays

The relationship between radiation exposure and cancer has been researched extensively for more than 100 years and it has been proven that radiation is only a weak carcinogen – in other words, it takes a very large amount of radiation to increase the risk of cancer only slightly.

Any cell phone at or below these SAR levels (that is, any phone legally sold in the U.S.) is a “safe” phone, as measured by these standards. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg).

The NRC does not regulate background radiation. But the NRC does require its licensees to limit exposure to members of the public to 100 mrem (1 mSv) per year above background. Exposure to adults working with radioactive materials must be below 5,000 mrem (50 mSv) per year.

There is no recommended limit on how many computed tomography (CT) scans you can have. CT scans provide critical information. When a severely ill patient has undergone several CT exams, the exams were important for diagnosis and treatment.

But for a healthy person, “it would be impossible to overdose on bananas,” says Collins. “You would probably need around 400 bananas a day to build up the kind of potassium levels that would cause your heart to stop beating… Bananas are not dangerous – and in fact they are, and always have been, very good for you.”

Bananas are one of the most popular fruits in the world. They’re full important nutrients, but eating too many could end up doing more harm than good. Too much of any single food may contribute to weight gain and nutrient deficiencies. One to two bananas per day is considered a moderate intake for most healthy people.

According to the National Council on Radiation Protection and Measurements (NCRP), the average annual radiation dose per person in the U.S. is 6.2 millisieverts (620 millirem).

Take a warm shower and gently wash yourself with lots of soap. Do not scald, scrub, or scratch your skin. Your skin helps protect the inside of your body from radioactive material. Wash your hair with shampoo or soap.

Human remains containing radiopharmaceuticals, which are buried in a grave or interred in a mausoleum crypt, pose negligible radiation risks to persons handling the coffin or in the vicinity of the burial site or mausoleum. There are several types of radiation that can be emitted from radioactive substances.

Radiation sickness occurs when high-energy radiation damages or destroys certain cells in your body. Regions of the body most vulnerable to high-energy radiation are cells in the lining of your intestinal tract, including your stomach, and the blood cell-producing cells of bone marrow.

The best choice, then, for burial of a body contaminated with radioactive material is a metal casket inside a concrete lined vault as shown here. It is common practice at the cemetery to lower the base of the vault into the grave, and then lower the cover.

Radioactive wastes are stored so as to avoid any chance of radiation exposure to people, or any pollution. The radioactivity of the wastes decays with time, providing a strong incentive to store high-level waste for about 50 years before disposal.

A process used to reduce, remove, or neutralize radiological, chemical, or biological contamination to reduce the risk of exposure.

Type B packages

Four types of packages will be discussed; Excepted packaging, Industrial packaging, Type A packaging and Type B packaging. Consideration for the mode of transporting radioactive material will be discussed.

RADIOACTIVE WHITE-I is the lowest category and RADIOACTIVE YELLOW-III is the highest. For example, a package with a transport index of 0.8 and a maximum surface radiation level of 0.6 millisievert (60 millirems) per hour must bear a RADIOACTIVE YELLOW-III label.

The type of radioactive shipment that needs to be made is based on the activity (Curie content) and radiation levels of the material being shipped. The UN Number is UN2910 and the hazard class is Class 7 (Radioactive).
