A 5.0 mL sample of cobalt-60 used in cancer therapy contains 2.00 mCi. How many becquerels are present? (Hint: notice that you have 2 milliCuries not Curies)
conversion to be used:
1 Ci = 3.7*10^10 Bq
we have:
2.00 mCi = 2.00*10^-3 Ci
= 2.00*10^-3 * 3.7*10^10 Bq
= 7.40*10^7 Bq
Answer: 7.40*10^7 Bq

(#22) Cobalt-60 is a radioactive isotope that is commonly used
for cancer radiation therapy. The cobalt-60 atom decays to the
stable nickel-60 atom, releasing a beta particle (electron) and
energy in the form of gamma rays:
If you captured the energy from the decay of a 1.19 g pellet of
isotopically pure cobalt-60, how long could you run a 60.0 W light
bulb? In hours
The relevant masses are as follows:
Gamma rays are massless.
