A worker will need to conduct a repair to a pipe containing radioactive waste. The pipe is 10 m long, and the worker will need to be standing 50 cm from the pipe. A remote detector was used to take a reading of 1.5 R/hr at 3 m from the pipe. a) What is the dose rate at the work position? b) If the worker's dose limit is 30 rad, how long will he have to complete the work? Assume that there is no dose from approaching and leaving the work location. O
