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.

(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

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?

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
