"1 mg (0.001 g) of the isotope 239Pu is placed inside a detector. 239Pu alpha-decays with a half-life of T1/2 = 24119 yr. Calculate how many alpha-particles from the decay will be detected in 1 hour. (Assume 100% detection efficiency)."
Could someone please show me how to do this question?
Thanks:).
