Question 7 1 pts (Calculation) Suppose you're working with a different radioactive species, one that has a half- life of 0.992 hours. You prepare your standard solutions and your unknown, you irradiate the solutions in the Am-Be source and then you count the resulting radioactivity in the scintillation counter. Your results are as follows: Solution # Count rate (CPM) Time E?:::dsst;me 1 143 0:11:21 2 190 3 274 Unknown 358 4 370 5 373 Blank 13 Assuming no well correction is required, calculate the corrected count rate for solution #5. Calculate that rate for elapsed time = zero. Give your answer to the closest integer
