Dianazene was the name given by L. Ron Hubbard to a vitamin compound containing iron, vitamin C, and various B vitamins, including especially large doses of niacin.. Hubbard promoted it as a form of protection against radiation poisoning during the 1950s, saying that "Dianazene runs out radiation — or what appears to be radiation.
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 electron volts (eV), which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms.
Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1]It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is the probability of cancer induction and genetic effects, of low levels of ...
In most power plant scenarios, where the radiation environment is dominated by X-or gamma rays applied uniformly to the whole body, 1 rad of absorbed dose gives 1 rem of effective dose. [5] In other situations, the effective dose in rem might be thirty times higher or thousands of times lower than the absorbed dose in rad.
Radiation exposure can be managed by a combination of these factors: Time: Reducing the time of an exposure reduces the effective dose proportionally. An example of reducing radiation doses by reducing the time of exposures might be improving operator training to reduce the time they take to handle a radioactive source.
For humans, the efficiency of conversion is estimated as requiring 60 mg of tryptophan to make 1 mg of niacin. Riboflavin , vitamin B 6 and iron are required for the process. [ 20 ] Pellagra is a consequence of a corn-dominant diet because the niacin in corn is poorly bioavailable and corn proteins are low in tryptophan compared to wheat and ...
Radiopharmaceuticals emit radiation themselves, which is different from contrast media which absorb or alter external electromagnetism or ultrasound. Radiopharmacology is the branch of pharmacology that specializes in these agents. The main group of these compounds are the radiotracers used to diagnose dysfunction in body tissues.
Example of a label showing the amount of niacin (Vitamin B3), and specifying to be niacinamide in the ingredient section.. As flour fortification started adding niacin in the US, the United States Government adopted the terms niacin (a shortened form of "nicotinic acid vitamin") and niacinamide in 1942 as alternate names for nicotinic acid and nicotinamide, respectively, and encouraged their ...
