What are the estimated standard deviation and the percent estimated standard deviation of the sample count rate corrected for background? [ad_1] 10-8. A 2048×2048×12-bit image is compressed at 10 to 1 compression ratio. How many bits are present in the compressed image? 11-1. Suppose 3600 counts were accumulated for a sample counted for 10
Explain how variations in the observed counts caused by fluctuations in the sensitivity of the counting system can be compensated. [ad_1] 9-7. A series of radioactive samples of short half-life will be counted one per day over several days. Explain how variations in the observed counts caused by fluctuations in the sensitivity of the counting
What was the total correction factor between the count rate and the activity of the system used to count 131I mounted on Mylar? [ad_1] 9-6. A 131I standard solution was obtained from the National Bureau of Standards (NBS). The following information was supplied concerning the solution: assay of 131I at 8 A.M., January 1, 2.09
