Question

In medical use, a good radioisotope tracer has the following characteristics

A. Long half-life
B. Gamma radiation
C. Decay to nontoxic form
D. Undergo the same reactions as nonradioactive elements

Answer 1

A good radioisotope tracer used in medical applications has a short half-life, gamma radiation, decays to a nontoxic form, and behaves chemically like non-radioactive elements.

Step-by-step explanation:

A good radioisotope tracer used in medical applications has the following characteristics:

1. Short half-life: Radioisotopes with short half-lives decay quickly, allowing for precise imaging and diagnostics.
2. Gamma radiation: Gamma radiation is highly penetrating and can be easily detected, making it ideal for medical imaging.
3. Decay to nontoxic form: After undergoing radioactive decay, the radioisotope should transform into a non-radioactive, non-toxic form.
4. Chemical similarity: Radioisotopes should behave chemically in the same way as their non-radioactive counterparts to accurately trace biological processes.
