A 7.5 gram sample of Sr-90 was formed in 1960. The half life is 28 years. In what year will only 0.9357 grams remain? Show work
Good morning I hope that you will be able to help me solve this problem? A given sample has two radioactive nuclei C and D. The half-life of species D is 1.68 days whereas that one ofC is unknown. Initially, they are present in equal amounts. Five days later, there are five times as many C nucleias there are D nuclei. Calculate the half-life of species C. Kind regards Rani

As a result of measuring beta particles emitted from P-32 for 2 minutes with a GM counter(Geiger), it was 72,960 counts. If a P-32 standard source having the same shape as this source and having a radioactivity of 2 kBq was measured for 10 minutes under the same conditions as before and 320,000 counts were obtained, what is the radioactivity of the first P-32? (required for solution course)
