Question

2. Determine how far the alpha particle can reach in 10 minutes of radiation (open system) 3. From the daughter's recoiled energy, E_n, determine if this energy is enough to break the chemical bound of its mother. 4. Calculate the speed of the daughter using the daughter's recoiled energy, E_n. 5. Pollution, in an open system, find the location of the daughter radioisotope in 10 minutes of the mother decay in an open container. Discuss why it is radiation pollution? Repeat 1-5 for the beta negative decay; could we have radiation pollution from the daughter? why?
