WebRadioactivity is a physical, not a biological, phenomenon. Simply stated, the radioactivity of a sample can be measured by counting how many atoms are spontaneously decaying each second. This can be done with instruments designed to detect the particular type of radiation emitted with each "decay" or disintegration. WebRadioactive objects are used in cancer treatments and medicines. Nuclear power plants depend on radioactive atoms. Radioactivity also kills germs in our food or is used to sanitize objects.
