Strontium 38Sr90 has a half-life of 29.1 yr. It is chemically similar to calcium, enters the body through the food chain, and collects in the bones. Consequently, 38Sr90 is a particularly serious health hazard. How long (in years) will it take for 99.9987% of the 38Sr90 released in a nuclear reactor accident to disappear?

9. Strontium-90 has a half-life of 28.8 years and has the same basic chemical properties as calcium. The nuclear testing 60 years ago resulted in some small amount of radioactive strontium-90 residing in all of our bones (us old folks, at least). Assuming the contamination remained in the body all those years, calculate the fraction ( N / No ) of that initial contamination still present in our bones. *Please include a diagram

(4 points) The half-life of radioactive strontium-90 is approximately 32 years. In 1964, radioactive strontium-90 was released into the atmosphere during testing of nuclear weapons, and was absorbed into people's bones. How many years does it take until only 9 percent of the original amount absorbed remains? time = 1 years
