This means it is the radiation responsible for ionising molecules. Small doses of radiation over a long period of time can cause the cells to multiply. Background radiation comes from the soil, rocks, the air, water, plants, building materials and food.
If this happens in our body, the cells may die or they may undergo a change called a mutation. Some radiation is due to cosmic rays from outer space.
If radiation collides with molecules in the air or in your body, it throws out of them electrons.
By throwing out electrons you produce charged particles called ions. We are surrounded by background radiation all of the time!
Two main uses of carbon-14 are in diagnostic medical procedures and radiocarbon dating to determine the age of previously living animals and plants.
In medicine, carbon-14 can be injected to study abnormalities of metabolism that underlie diabetes, gout, anemia, and acromegaly (adult “gigantism”), and to trace the metabolism of new drugs.
Gamma rays successfully kill microbes that cause food to decay.What methods do they use and how do these methods work?In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.If all samples in a batch are unsuitable for dating, we reserve the right to charge an inspection fee of NZD50 plus the MPI fee of NZD35.^ Measured by CRDS (precision 0.3 per mil). Please read our pages on sample weight requirements, and if you are unsure about the suitability of your sample please contact us.Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days? He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.
