Standard unit of ionizing radiation dose is Sievert. I can get a rough idea of how dangerous absorbing various amounts is from https://xkcd.com/radiation/ and other sources. There are many other measurements related to radiation (https://www.nrc.gov/about-nrc/radiation/health-effects/measuring-radiation.html). I understand that these units measure different things and are not comparable. I would like to get a feeling for their order of magnitude, if possible.
For example, I am looking for something like (I apologize in advance for stupidity of what I am about to write, it is supposed to only illustrate the kind of answer I am looking for): 1 becquerel during 1 minute carries X to Y joules (depending on the type of decay), and when absorbed by an organ weighing 1 kilogram produces a dose of Z sieverts.
Is this at all reasonable?
