Physics written by hand.
Mantles for gas lanterns contain thorium, because it forms an oxide that can survive being heated to incandescence for long periods of time. Natural thorium is almost 100% 232Th, with a half-life of 1.405 ✕ 1010 y. If an average lantern mantle contains 390 mg of thorium, what is its activity (in Bq)? Answer in Bq.

The 192Ir is used as a wire and inserted near the tumor for a given amount of time and then removed. The 192Ir wire is coated with pure platinum, and is sold by diameter and amount of radiation emitted. One type of wire sold is 221 mm long, has a linear apparent activity of 30–130 MBq/cm, an active diameter (which is the iridium-192) of 0.1 mm, and an outer diameter (the platinum) of 0.3 mm.
