08.01- Half-Life and Radioactive Decay
Transcript of 08.01- Half-Life and Radioactive Decay
and Technology Carbon-14 is naturally found in the atmosphere
Natural Abundance is one part per trillion
Carbon-14 decays into Nitrogen-14 through Beta Decay
Because beta particles are small and fast, they can penetrate the human skin and potentially cause damage to celsl Thin sheets of metal can protect from beta particles, and absorb the material like an electron
The U.S. Environmental Protection Agency states to simply stay away from radioactive areas, which are clearly marked with signs Carbon-14 is the primary basis of carbon dating, which is used to date archaeological, historical, and geological artifacts Works Cited U.S. Environmental Protection Agency.

It is used in a pill to eliminate thyroid cancer.
The thyroid naturally absorbs iodine, so the cancerous tissue takes in the radioactive material and is subsequently destroyed The benefits of iodine-131 are that it will eliminate cancer of the thyroid glands
The risks involved are that it may damage other, healthy tissue.
It is used commonly to eliminate this type of cancer American Association of Clinical Endocrinologists. (2004). www.kmuc.edu.
