Determination of the half-lives of transactinium isotopes by relative activity method
- 40 Downloads
Relative activity method offers the potentiality of providing half-life values over a wide range in a short time for different α-emitting transactinium isotopes. The method involves the preparation of a synthetic mixture using another isotope of the same element followed by the determination of atom ratio and α-activity ratio by thermal ionization mass spectrometry and α-spectrometry, respectively. A double dilution technique is described which helps in maintaining the atom ratios as well as α-activity ratios close to unity so that these could be determined with high precision and accuracy. Results obtained on the half-lives of232U,238Pu,242Pu and243Am using double dilution technique in relative activity method are summarized. Requirements, advantages and applications of this technique for determining the half-lives of other transactinium isotopes are presented.
