3. Take the Cookie Challenge. You have four (4) radioactive cookies of equal activity emitting: (i) alphas, (ii) betas, (iii) gammas, and (iv) neutrons. You must do one of the following: (a) put one of the cookies into your pocket, (b) throw one cookie as far as you can, (c) eat one of the cookies, and (d) hold the remaining cookie in your hand. Match each cookie to the respective action that minimizes your dose equivalent. Clearly explain your reasoning based on the physical principles discussed in class. (Hint: think about quality factor and penetration depth of each particle). Discuss any factors which may complicate your choices.
