Both. Radioisotopes decay because they are atomically unstable. This can be used to advantage in medical treatment or diagnosis and in other forms of research or inspection. But radioactive decay releases ionizing radiation, and that is invariably harmful to living tissue. The problem presents as one of weighing the cost-benefit ratio of a given application. As just one example, radiation kills tissue, but it kills cancerous tissue much more readily than "regular" tissue. This makes radiation tratment by radioisotopes beneficial in cases where other options are limited.
The half-life of the radioisotope Na-22 is 2.6 years.
The radioisotope with the shortest half-life among the following options is Polonium-214.
If a radioisotope undergoes six half-lives, only (1/64) or (0.015625) of the original radioisotope remains, because half of the remaining material decays at each half-life.
One-half of the original amount. That's precisely the definition of "half-life".
The half-life of a radioisotope is the time it takes for half of the radioactive nuclei in a sample to decay. It is a characteristic property of each radioisotope and determines the rate at which the isotopes decay.

it depends on the type of the bacteria. also beneficial bacterias outnumber the population of harmful bacterias.
