It’s probably 7000 cGY, which equals 70Grays converted. I don’t know why the conversion, but have seen both. Maybe cGY on radiation reports, which name I forget. You may find radiation very complex as it is for me and many others.

Also, there is no max lifetime radiation dosage. Maybe whole body in one day over a maximum Gray. I thought I heard 100? There are maximum dosage for certain structures before toxicitie limits, but their pushing radiation, and other areas more, if they can. I had total dose of 210Gray to my left neck, but not without some issues like ORN, Brachial Plexopathy to my left radiated neck, if it’s related to that. I had a jaw replacement and left arm complete paralysis, but was worth it to be cancer free.
