- Homework Statement
- the isotope 99Tc decays to another isotope
Explain why this decay of 99Tc will not cause much damage in the body?
- Relevant Equations
- Knowledge of Radioactive decays
The question also considered 99m-Tc which has a 6h of half-life. And 99Tc has about 2.2E5 years. My argue was, “the half life of 99Tc is greater than the lifespan of a person. So ionization energy that is released has minimal effect to the person compared to Tc-99m which decays (and releases energy) every 6 hours.
Is this statement correct and enough?
