Concept explainers
INTERPRETATION:
The percentage of thorium decomposed after the given period of time should be determined using the concepts of half life.
CONCEPT INTRODUCTION:
Radioactive decay:
A nucleus undergoes disintegration in-order to become stable by emitting radiations such as alpha, beta and gamma particles.
Radioactive series:
The series in which successive disintegration of unstable nuclei is formed until a stable nucleus is formed.
Half life:
The time used for the decay of the half of the radioactive isotope to undergo decay.
Equation for number of half lives passed:

- 239Pu is a nuclear waste byproduct with a half-life of 24,000 y. What fraction of the 239Pu present today will be present in 1000 y?arrow_forwardA laboratory investigation shows that a sample of uranium ore contains 5.37 mg of U92238 and 2.52 mg of P82206b. Calculate the age of the ore. The half-life of U92238 is 4.5109 yr.arrow_forwardDefine the term half-life and illustrate it with an example.arrow_forward
- The isotope 208Tl undergoes decay with a half-life of 3.1 min.. (a) What isotope is produced by the decay?. (b) How long will it take for 99.0% of a sample of pure 208Tl to decay?. (c) What percentage of a sample of pure 208Tl remains un-decayed after 1.0 h?arrow_forwardTechnetium-99m has a half-life of 6.01 hours. If a patient injected with technetium-99m is safe to leave the hospital once 75% of the dose has decayed, when is the patient allowed to leave?arrow_forward
