Need help on absorbed dose problem

[wiesner1]

I have a problem that asks:

What is the absorbed dose rate to water if it contains 1 GBq kg-1 of 3H?

I guess what I am looking at is an infinite medium with concentration C (Bq kg-1) with ionizing energy per transition Q (J). Then the formula is D=QC

First of all, is ionizing energy per transition for H3..is that just the decay energy?

Then, would I have to take 0.018590 mev (that is what I find for H3 decay energy), convert the units of Mev into grays to come up with an answer?
Help! Terrible at math! I appreciate any help. I'm very dedicated to learning this stuff, but I kind of suck at it!

why wood yew want the absorbed dose to a solvent from a solute?
eye can see seeking the absorbed dose to a conduit from a solvent with a radiological solute as a matter if concern.
unless yore out fore blood....
