I mean, most people probably know RADS from the fallout games, perhaps even Greys (which is 100 RADS)... Rems?

But what about Seiverts? Curies? Becquerles! (which apparently a million of them make a Rutherford)

And then there's Canada's DarkCobalt project... apparently while Canada is considered an insignificant military threat, we have the capability of creating the most "dirty" bombs thanks to our high quantity and quality of Cobalt-60 production... moreso than even Russia

Gray (the SI unit) is commonly used in radiation therapy. J/kg. Rads is less common for me, but its basically a cGy and other fields use it I think.

Sievert has the same units of a Gy but its more used in the health effects area, how likely you are to get cancer. Theyre completely different even though the units are the same. Rem is used also and is a scaled Sievertkinda like rad is used also.

Now, the units I already mentioned above are absorbed dose. You also have activity. Curies are super common and are the standard when people talk about activity. Bequerels are important for calculations and are more fundamental.

BED: Radiation health effects per mass

I wouldnt lump it in with Sievert and REM. Its more used to put info into perspective and is measured in Gy. There are Equivalent and Effective doses which are more related to Seivert and REM, but BED Ive always known to be reserved to refer to a specific thingI view it like a filter.

Edit: Or are you talking about banana equivalence and not biological equivalence?
