Radioactive substances

1. Radioactive substances have a number of important uses. Doctors use radium to destroy cancers. Radioactive substances found in rocks or relics of prehistoric man can also be used to find out how old the rocks or relics are. Paints containing a tiny bit of radioactive material and a substance that radioactivity causes to glow are used for self-illuminated watch and clock dials.

2. In addition to the naturally radioactive substances, there are many in which radioactivity can be induced by bombarding them in an atom smasher or placing them in an atomic reactor. Many of these "radioisotopes" (as they are called) are extremely useful. Thus, cobalt-60 can be used in place of radium for treating cancer. Patients with cancer of the thyroid gland can be treated merely by swallowing a bit of radioiodine; the radioiodine will find its way to the thyroid gland, where its beta rays can attack the cancer.

3. Radioisotopes can be used both in industry and in scientific research, too. Since radiations passing through thin materials are stronger than those passing through thick materials, radioisotopes can be used to measure the thickness of steel plates and other metal objects. Or a bit of radioactive material can be incorporated in tyres or engine parts. Then the amount of wear can be studied by measuring the radioactivity in particles worn off. Radioisotopes can also be mixed with fertilizer and traced with a Geiger counter to see what happens when plants take up fertilizer; or they can be mixed with food to trace what happens to the food eaten by animals.
