Dear Sirt-
We do not bolieve that Radivun boins could occur from hendling
commercial celf-Juninous material. Products of this ldnd are handled in
small quantities and the amount of Radiom contained is mintte. Ordinary
commercial grades used on watches, clocks, etc. contain only a fow cente
worth of Radium per watch or clock.
Radivun bozns occur from hondling concentrated Radium salts. It
is conceivable to visualize a very large quantity of Radium Imminous Material
conteining 100 Mg. or 200 Mig. or more milligrems of Radium that would canse
a burn if it were concentrated in one place and some one was held in close
contact with it for a considerable period of time. Even then the difrusión
might be too great to cause a concentrated effect. The intensity of Radium
rays diminishes inversely as the square of the distence so that for therapeutic
work highly concentrated salts are now genorally packed in the smollest
possible containero and inserted directly into the tissos.
If when writing your letter of June 3 you had in mind a particular
case of Radium buxn or bum of unicnow origin, tre should be glad to have the
particulars.
Yours truly,
President.
