Abstract: Finding the half-life of Aluminum-28 is the purpose of this lab. The class met at the Radiation Center and exposed small amounts of aluminum to energetic neutrons and watched the samples decay. After creating a table with background count and gross counts of the aluminum remaining at fifteen different one-minute intervals‚ this allowed the net counts per minute at each interval to be found as well. Next a graph of the net cpm verses time was plotted. After each interval was plotted

society have to worry about treating and containing the wastes; we also have to find sites to store the waste that will not allow it to spread‚ even under the worst situations. There are many classifications of waste. Spent nuclear fuel is the radioactive by-product of making electricity at commercial nuclear power plants. This form of waste contains hazardous chemicals and toxic heavy metals. It is also considered to be environmentally hazardous for thousands of years after it is used.

One of the scariest things about nuclear power is when something goes wrong and an accident occurs. Radiation is released into the environment and people get hurt. Two of the most famous nuclear accidents occurred at the Three Mile Island reactor 2 in the United States and the Chernobyl reactor 4 in the former Soviet Union. In this text we will discuss these two disasters‚ along with correcting a few common misconceptions about nuclear accidents. The worst type of man-made disaster is caused by

the operations done by the staff were highly questionable) 2. Radioactive Waste : Radioactivity naturally decays over time‚ so radioactive waste has to be isolated and confined in appropriate disposal facilities for a sufficient period of time until it no longer poses a threat. Radiation exposure can also cause cancer‚ birth defects‚ and other abnormalities‚ depending on the time of exposure and amount of radiation. High-level radioactive waste from nuclear reactors can be hazardous for thousands of
