Sadly Wikipedia is not secure, it is editable by almost anyone, often
the info is interesting but not necessarily reliable.  I have not got a
clue on this particular question, but in 5 years of teaching DOE
RadWorker Training and 2 years a dosimetry technician, I have not heard
that definition either.

According to the Wikipedia entry for 'Rad', it was defined from 1918 to
1953 as the unit of X-ray dose required to kill a mouse. 1) I never
heard this definition before and 2) This seems like a very low dose for
killing anything.


This is somewhat before my time and I normally use SI units. Is the
Wikipedia statement correct?
