If 119 grams of a material absorbs 13 Joules of energy from radiation, what is the absorbed dose to the material? (Answer in Gray, round to the nearest single decimal place) Question 2 If 10 g of of tissue is uniformly irradiated and receives a dose of 1 cGy, what is the dose (in cGy) to half of this tissue?
When a star has exhausted its hydrogen fuel, it may fuse other nuclear fuels. At temperatures above 1.0 x 10° K, helium fusion can occur. Write the equation for the following processes. (a) Two alpha particles fuse to produce a nucleus A and a gamma ray. What is nucleus A? (Enter the mass number in the first raised box, the atomic number in the second lower box, and the element, with charge if necessary, in the third box.) (b) Nucleus A absorbs an alpha particle to produce a nucleus "B" and a gamma ray. What is nucleus B? (Enter your answer using the same format as above.) (c) Find the total energy (Q) released in the reactions given in parts (a) and (b). Note: the mass of 4 = 8.005 305u. MeV
