Reply to comment by Janezo in A medical isotope made from nuclear weapons waste (Tc-99m) has a six-hour half-life. How do hospitals keep it in stock? by Gwaiian

If it’s safe to have it injected it in you, it’s safe to be around someone who will cough out maybe 0.001% of what they had injected into them. Especially with such a short half life

Not have the medical imaging done seems more risky health wise then some radiation.

Exactly. But that doesn't mean that the radiation is "safe", which is what I responded to.
