Question: 2) A 0.1 Ci 22Na point source (Appendix D: 179.80% - 511 keV and 99.94% - 1,274.5 ke V) is stored at the center of

2) A 0.1 Ci 22Na point source (Appendix D: 179.80% - 511 keV and 99.94% - 1,274.5 ke V) is stored at the center of a spherical water tank 25 cm in diameter. Make a clear diagram for this problem, and show your calculations and unit work.

(a) What would be the equivalent dose rate (in rem/s) absorbed by a bystander right next to the tank? Compare this number with the natural dose (US average ~ 310 mrem/year).

(b) What percentage of the total dose absorbed by the bystander is due to each y-ray energy emitter the 22Na source. Compare and comment.
