Question

130 decays by emission of beta particles to form stable 130xe. A 3.00 g lodine sample containing some I-130 was recorded as having
5652 disintegrations per min, k = 0.00094 min . How many radioactive l-130 atoms are present in the sample?
Answer:
The radioactive decay a sample containing an unknown radioactive isotope produced 8961 disintegrations per minute. 15.78 days
later, the rate of decay was found to be 3328 disintegrations per minute. Calculate the half-life in days for the unknown radioactive
isotope.
Answer:
The half-life of carbon-14 is 5,730 years. An artifact produces 1.4 disintegrations of 14C per minute per gram of carbon in the sample.
Estimate the age of this sample assuming that its original radioactivity was 15.3 disintegrations per minute per gram of carbon.
Answer:
A certain radioactive element has a half life of 3610 years. How much of a 4.16 g sample is left after 4231 years?
