You are an operator on facility with stored radioactive materials, and that portion of the facility has experienced a fire. Since you know the region of the facility where the fire took place, you are being asked to help lead a team to identify, characterize and eventually secure any possible radioactive sources that might have been exposed in the incident.Choose the most appropriate piece of equipment for each task the team is likely to have to perform. Some answers may be used more than once, some may not be used.

Fill in each blank with the most appropriate term. Some answers may be used more than once, some may not be used.In (1) ______, changes occur within an atom’s nucleus rather than its electron cloud. Each nuclide is defined by its (2) ______ (number of (3) ______) and its (4) ______ (sum of (5)________). Writing a (6) ______ requires that both the total mass numbers and atomic numbers balance, reflecting the (7) ______ of mass and charge. Unstable nuclides may emit an (8) ______ particle — a high-energy helium nucleus — reducing mass by 4 and atomic number by 2; a (9) ______ particle — a high-energy electron, converting a neutron to a proton; or a (10) ______, shedding excess energy with no change in mass number or atomic number. The rate of decay follows an exponential law characterized by a nuclide’s (11) ______.

Technicium-99m is a radioisotope that is widely used in medical imaging procedures. It is supplied to hospitals in a lead-shielded pot which contains a sample of molybdenum-99 that is generated in a nuclear facility — a nuclear power plant. The molybdenum-99 decays to technicium-99m, and samples of technicium-99m are obtained for medical procedures in the hospital by rinsing the molybdenum sample with a saline solution that specifically solubilizes the technicium. If the molybdenum–99 has a half life of 66 hours, and the hospital needs at least [x] percent of the molybdenum in its undecayed state for the sample to be useful, how long does the supplied sample remain useful to the hospital? Report your answer in days, and round to an integer number of days (i.e., 5, 17, 24, etc.)
