Ionising radiation, such as gamma rays, X-rays and radioactive particles can cause cancer by damaging DNA. However, how this happens, or how many tumours are caused by radiationdamagehas not been known. Previous work on cancer had revealed that DNA damage often leaves a molecular fingerprint, ...

Radioactive Decay Remember that radioactive decay is a random process which cannot be predicted or determined for a single atom. The rate of decay is controlled by the amount of nuclei present so over time the activity decreases exponentially This means that in a set time period the activity w...
On Earth, DNA rarely, if ever, survives much longer than a million years. In principle, however, DNA kept at a few degrees above absolute zero and protected from harmful ionising radiation could survive indefinitely. Life permeates the entire crust of the Earth. As theDeep Carbon Observatory ...
It is synthesized by the thyroid gland and used to control our metabolism. If radioactive fission products iodine 132 or 131 enter the body, the thyroid cannot distinguish them from the stable iodine 127. The radioactive iodine decays, emitting beta and gamma radiation which is known to cause...
