Radiopharmaceuticals radiomodifying agents

@_brauer_ yeah, as far as I know, the bone marrow is most damaged by strong radiation

@elizaveta-msu thanks, I see

what substances can enhance the effect of radiation on the body?

@marie-curie any radioactive substances.. What do you mean?

@morphism I think the question is about ordinary, non-radioactive compounds that can be present in the body and by radiation enhance the effect of this radiation

@marie-curie substances whose intracellular content enhances the radiobiological effect include oxygen, lipid hydroperoxides, a group of quinones, etc. For example, when tissues are irradiated in the presence of oxygen, a large number of radicals and peroxides appear in it, which enhance oxidation processes, and a large number of chain reactions can also begin 

by the way, as far as I know, cancer cells are sometimes oxygenated to increase the effectiveness of therapy

@_brauer_ okaay, it means that by radiomodifying agents we mean substances that modify ("enhance/gain") radiation?

@morphism I think, it's more correct to say, that these substances modify the biological effect of the radiation instead of "they modify the radiation". But yeah, radiomodifying agents can both enhance the effect of radiation and gain it

@_brauer_ ok, now it's clear
