Hi!
I was wondering what "Commercial" part means in "Commercial Radioisotopes".
Can somebody tell me?
Thanks!

   Commercial radioisotopes are isotopes that you can find them in commerce, as the word means.(Not any person and so easy. For some of them-you must have a special permission) E.g CO60, is a radioisotope that used in medicin for cancer treatment. So hospitals buy it from the apropriate source. Commercial= "is moving to the market''.

Yup.  And some more examples would be Am-241 which is found in smoke detectors, Th-232 which used to be used in gas lantern mantles and is still used a tiny amount in lightbulb filaments, and a few others.
