Dear Radsafers,
I wonder if anyone could point at a graph showing the total of the most
important gamma and beta (90Sr essentially I believe.) in spent nuclear
fuel. This is not about the risks as described by dilution in water.
The example could come from some typical BWR or PWR plant.
Which gamma emitting radionuclides must be considered besides cesium 137 say
in the time interval 40 yrs (taken as time for long term storage) to 1000
yrs?
Are there any other dominating beta emitting radionuclides besides Sr 90.
If there are just a few dominating gamma radionuclides, please then give
them in their approximate relative proportions from time "zero" or after say
40 yrs.
Any help will be much appreciated.
Best regards,
