UNITED The activity of ? Na sample (E, = 1.275 MeV, 1.- 0.99934, and tun 2.6022 y) is needed for October 11, 2016 The source was counted on October 11, 2006 on a 0.22% efficient Geiger-Mueller (G-M) detector system. The results were 1.50 x 10 counts during a 400 second live time. The sample was created on October 11, 2001. 4 pts) Determine the time (T) between the count dates in units of years: Answer: 15 years No solutions hovedd for Q's 2-8. (4 pts) Determine the counts per second (ops) on October 11, 2006: X(9 pe 15 Answer: 4 (4 pts) Determine the activity (UCI) on October 11, 2006: Answer: Bf4 pts) Determine the activity (nci) on October 11, 2021: Answer: to pre . pts) Determine the original activity (HCI) on October 11, 2001: Answer: (4 pts) What is the probability (G) that a gamma ray will strike a 2-inch diameter and 4-inch long G-M detector which is placed 9.3 cm from a radioactive source? Answer: A source of 60.0 mCi is equivalent to how many MBq? Answer: CA (419 X(4 pts) The net count rate is the # counts/ live time. Determine the live time () for a detection system with a 15% dead time and a 1200 second real (clock) time. Answer: Yoyo pts) Trucor False Gamma rays following Beta decay appear with an energy characteristic of the Parent and the half-life characteristic of the Daughter. (Circle One)
