Step by step
Solved in 2 steps with 2 images
- A certain radioisotope has a half-life of 8.96 days. What percentage of an initial sample of this isotope remains after 25 days? Number i UnitsWould you kindly explain step by step as you answer the following question... A sample of material contains one milligram of Iodine-131. Iodine -131 has a half - life of 8.02 days. Find:a) The number of atoms of iodine-131 initially presentb) The activity of the sample in becquerelSuppose that you want to find out how much gasoline is in an underground storage tank. You pour in 1 gallon of gasoline that contains some radioactive material with a long half-life that gives off 5000 counts per minute. The next day, you remove a gallon from the underground tank and measure its radioactivity to be 10 counts per minute. How much gasoline is in the tank?
- Classify each of the following as units for radiation dose or units of radioactivity? a) Radiation b) radioactivity REM c) Becquerel d) Rad e) Seivert f) Curie1. A radiopharmaceutical has a physical half-life of 360 minutes and a biological half-life of 20 h & 15 minutes. How long will it take for the activity in the patient to fall to a quarter of a percent of that injected?You have been hired by a company interested in establishing a radioisotope production plant in your city where there is growing resistance against the plant because of ignorance in the uses of radiation. Convince the peopleat a town hall meeting by listing three different applications (uses) of radioisotopes/radiation.
