- The radioactive glucose used in PET scans has a half-life of approximately 2 hours. How much of the original radioisotope remains 8 hours after being injected in a patient?question 4 pleaseWhat experimental parameters help protect those who work regularly with radioactive materials and why? Radioactive decay is an inherently random process. In order to make our radiation counting measurements better, what could you do to increase the precision of your measurements? If the radioactive samples are not brand new, then how does the relative age of the sample affect your measurements?
- Give three (3) examples of uses of Radioactivity (for example, in archaeology, engineering, nuclear power plants, etc.), explain them.Prehistoric cave paintings were discovered in a cave in France. The paint contained 13% of the original carbon-14. The half-life of carbon-14 is 5730 years. Estimate the age of the paintings. The paintings are about years old.
