Radiation dose

Very rough estimation of the radiation dose/hour one meter away from a fuel array filled with spent light water reactor fuel as a function of time. The initial composition based on table 1 in aries.ucsd.edu/snowmass/SG-A/ans96-transmutation_paper.pdf
and the initial radioactivity by figure 1 in

The green lines mark the acute effects after one hour exposure. I have added the contributions of various isotopes in blue, but not taken daughter products into account.
