We are in agreement with you that the amount of raaioactive lead ingested by the laboratory worker at Columbia University was probably insignificant in terms of a health hazard. However, this was the first time uhat we were presented with this situation and for that reason we are anxious to have a proper under standing of the problem. Je are also particularly interested In the relationship of Radium D (which is Pb^lQ) to the inhalation of radon. J3 plan on getting one specimen next week and another in the middle of July. 'Then the radioactivity measurements are completed on both specimens, I will send than to you and we can then discuss the significance of the results. Let me express our appreciation for your help in this interesting problem. Sincerely yours. Roy S. Albert, M. D. Medical Officer Realth and Safety Division
