Assume you have a radioactive spill of 9tc and you are measuring it using a large volume gm tube detector in the shape of a flat disc. you measure 1 counts per minute at a distance of 1 cm from the contaminated surfac a. what detection geometry will you assume for your calculation? b. what is your estimate of the counting efficiency of this geometry? c. what is the activity of the spill? d. if it was decided to leave it there without cleaning it off the surface, how long would it be before the activity was indistinguishable from background radiation of 25 counts per second (assuming it would be within 2 standard deviations of background)? how dangerous is this spill?
