a) Determine if the waste is radioactive. Step 1: Compare initial activity to background radiation. The initial activity of the waste at time t=0 is 600 counts per hour. The background radiation in the area is 50 counts per hour. Step 2: Conclude based on comparison and trend. Since the initial activity (600 counts/hour) is significantly higher than the background radiation (50 counts/hour) and the activity decreases over time as shown in the table, the waste is radioactive. b) Determine half life of the sample. Step 1: Analyze the observed activity data for halving patterns. The half-life is the time it takes for the activity of a
