Attn: Dr. Leonard Groenburg, Executive Director Gentlemen: We have your letter of September 27th transmitting to us reprints of the New York State Industrial Bulletin rolative to the subject of "radium poisoning" and its prevention.

Rule 17. Tie provide separate hoods for weighing our luminous material, such hoods being provided with artificial vontilation and other conveniences for quickly and easily weighing o.t material. Vie do not require the use of rubber gloves in this op ration, as our ex- perience indicates that the work can be done without getting the material on the hands, and with the ventilation provided, wJ do not feol that there is any dangor of the material impregnating either the clothing or hdnds of
