After the release of radioactive material into the atmosphere from a nuclear power plant in a country in 1990, the hay in that country was contaminated by a radioactive isotope (half-life 7 days). If it is safe to feed the hay to cows when 15% of the radioactive isotope remains, how long did the farmers need to wait to use this hay?

lodine 131 is a radioactive form of iodine. After the crisis at a Japanese nuclear power plant in March 2011, elevated levels of this substance were detected thousands of miles away from Japan. Iodine. 131 has a half-life of days. What is the daily decay factor for this substance? (Round your answer to two decimal places)

After the sudden release of radioactivity from the Chernobyl nuclear reactor accident in 1986, the radioactivity of milk in one region of Poland rose to 1450 Bq/L due to iodine-131 present in the grass eaten by dairy cattle. (Note that the radioactivity was higher in other regions of Poland.) Radioactive iodine, with half-life 8.04 days, is particularly hazardous because the thyroid gland concentrates iodine. The Chernobyl accident causeda measurable increase in thyroid cancers among children in Belarus. (a) For comparison,...

Buckeye Nuclear Power is a nuclear plant that provides
electricity for southern Ohio. There was an accident and iodine-131
was emitted into the atmosphere. The half-life of iodine-131 is 8
days. If a total of 200 g of iodine-131 was emitted, how much
131 I would remain after 3 months? Show all of your work
and report your answer in % remaining.

Cesium-137 is a radioactive isotope of cesium. Cesium-137 was emitted from the explosion of the Fukushima Nuclear Power Plant, Japan, last month. It is known that the half life of Cesium-137 is 30.17 years. The decay of Cesium-137 follows the first-order kinetics. (1) Determine the reaction rate constant. (2) How long will it take to reduce the emitted quantity by one tenth?

Question 4: Carbon dating (3 points) Archaeologists use the exponential, radioactive decay of carbon-14 to estimate the death dates of organic material. The stable form of carbon is carbon-12, and the radioactive isotope carbon-14 decays over time into nitrogen-14 and other particles. Carbon is naturally in all living organisms, and the carbon-14 that forms in the upper atmosphere enters into living things as long as they are taking in material (food, air, etc.) that contains carbon. We...
