WebBiological Half-life. The radioactive half-life for a given radioisotope is physically determined and unaffected by the physical or chemical conditions around it. However, if that radioisotope is in a living organism it may be excreted so that it no longer is a source of radiation exposure to the organism. ... 226 Ra: 5.8 x 10 5: 1.6 x 10 4: 1 ... WebApr 7, 2024 · Now the formula to calculate the half-life of a radioactive element is- t 1 / 2 = 0.693 λ where λ is the disintegration constant or decay constant. It is defined as the fraction of total number of atoms which disintegrate per second at any time. Now to find out the half-life of radium we first need to calculate the disintegration constant.
