The half life of a radioisotope indicates the rate of decay for a radioactive sample
Dear Sir All the medicine have half life. half life is the time that when 50 per cent of drug goes out of the body. it is important because when the kidney or liver failure exist the drug remains in body and toxic reactions occurs. ------ See the link below for the half-life of radioisotopes.
They decay at a predictable rate.
Radioisotopes are used in nuclear reactors as fuel to generate heat through nuclear fission. The heat produced is used to generate steam, which drives turbines to generate electricity. Radioisotopes such as uranium-235 and plutonium-239 are commonly used in nuclear reactors.
By definition, 50%. Half life is the time for half of the original sample to decay.
Uranium has a high half-life, so it changes very quickly.
The half-life
there are a wide range of radioisotopes with varying properties such as half-life, type of decay, and energy emitted. Some radioisotopes are more stable and have longer half-lives, while others decay quickly and emit different types of radiation. The properties of radioisotopes are important when considering their applications in medicine, industry, and research.
The Terbium isotope found in nature (159Tb) is stable. Like all elements, Terbium has radioisotopes, of which 33 have been created to date. 158Tb is the most stable of these, with a half-life of 180 years, 157Tb has a 71 year half-life. 160Tb has a half-life of 72.3 days. Most of the remaining radioisotopes have half-lives that are less measured in seconds, although some have half lives that are measured in days.
Radioisotopes are "radioactive isotopes"; they are not stable. Radioactive atoms will decay, or break apart into other atoms, by emitting an electron, or a neutron or a positron or an alpha particle (2 protons and two neutrons). The rate at which this happens is measured by the "half-life"; after one half-life, half of the atoms will have decayed. After another half-life, half of the remaining atoms will have decayed. Atoms with short half-lives are highly radioactive, and can be fairly dangerous. Atoms with long half-lives are only slightly radioactive, and aren't all that dangerous.
A short half-life means the material only remains radioactive for a short time and does not continue to release radiation into the patient or environment.

Radioisotopes are not salts but salts may contain radioisotopes.
