Care must be taken when handling some of the residues as they contain 228 Ra, the daughter of 232 Th, which is a strong gamma emitter.
12.
The main reason for its wide use in radiotherapy is that it has a longer half-life, 5.27 years, than many other gamma emitters.
13.
The main disadvantage is that it is difficult and dangerous to reprocess the used fuel because many of the daughters of 232 Th and 233 U are strong gamma emitters.
14.
Soft tissues of animals can be analyzed for gamma emitters, bones and liver for strontium and plutonium, and blood, urine and soft tissues are analyzed for tritium.
15.
The most common gamma emitter used in medical applications is the nuclear isomer technetium-99m which emits gamma rays in the same energy range as diagnostic X-rays.
16.
If the protactinium remains in the reactor, small amounts of U-232 are also produced, which has the strong gamma emitter Tl-208 in its decay chain.
17.
Because U-232 has a short half-life and its decay chain contains hard gamma emitters, it makes the isotopic mix of uranium less attractive for bomb-making.
18.
A detailed analysis of this spectrum is typically used to determine the identity and quantity of gamma emitters present in a gamma source, and is a vital tool in radiometric assay.
19.
In contrast, sodium will form the potent gamma emitter sodium-24 ( half-life 15 hours ) following intense neutron radiation, requiring a large radiation shield for the primary cooling loop.
20.
For instance, the Americium article says that the radioactives found in your smoke detector release three times the amount of alpha particles as radium, and in " gram quantities " are intense gamma emitters.
