Radioisotope activity refers to the rate at which a radioactive element decays, emitting radiation in the process. It is measured in units of becquerels (Bq) or curies (Ci) and is used to determine the intensity of radiation emitted by a sample.
Radioisotope activity is measured using specialized equipment such as a Geiger counter or scintillation counter. These instruments detect the radiation emitted by the sample and convert it into a measurable signal, which can then be used to calculate the activity of the sample.
Biological half life refers to the amount of time it takes for half of a radioactive substance to be eliminated from the body through natural processes such as metabolism and excretion. This is important in assessing the potential health effects of exposure to radioactive materials.
Biological half life is determined through experiments in which a sample of a radioactive substance is administered to a living organism and the rate of elimination is measured over time. This data is then used to calculate the biological half life of the substance.
The activity of a radioisotope can be affected by factors such as temperature, pressure, and chemical reactions. Biological half life can be influenced by factors such as age, health, and the presence of other substances that may interact with the radioactive material in the body.
