I have attached the question below.

2. Relevant equations

I'm not sure how to answer the question.

3. The attempt at a solution

I started by calculating the specific dose rates for each isotope, but I cannot get any data for^{90}Sr using: http://www.nucleide.org/Laraweb/index.php

This is what I have so far.

For 1000 Bq of^{137}Cs, 850 photons per second are emitted with an energy of 662 keV. This equals a specific dose rate of 84 μSv/h/GBq at one meter. For 1 μCi this is 84 μSv/h/GBq x 10^{-6}x 37 GBq = 3108 μSv/h.

For 1000 Bq of^{131}I, 810 photons per second are emitted with an energy of 364 keV. This equals a specific dose rate of 0.4 μSv/h/GBq at one meter. For 2 μCi this is 0.4 μSv/h/GBq x 10^{-6}x (2X37 GBq) = 2.96X10^{5}μSv/h.
