Relationship of absorbed dose (Gray) to cf-252 activity (milicurie/hour)

1. The problem statement, all variables and given/known data

Hi there, I wanted to use TLD badges for my experiment using cf-252 instead of chips because they were the ones available. I was informed by the Laboratory section that the TLD had a max absorbed dose of 10 Gray. The neutron source cf-252 has an activity of 50 milicurie/hour.

2. Relevant equations

I googled up the relationship of absorbed dose with neutron source activity.. Maybe i was not sure. But i found that:
Absorbed Dose Constants for a variety of radionuclides, given in units of gram-rad (g-rad) per microcurie-hour (uCi/hr).
Absorbed Dose Constants are specific to the type and energy of the radiation emitted during the decay of the radionuclide.


3. The attempt at a solution
i foundthis out;
In the first week of therapy, 6 Gy (40 Gy‐eq) of the 252Cf neutron component are
applied. And in the fifth week of therapy 16 Gy absrbed dose dose of gamma radiation are given intracavitary
