Powers, ' will also" be involved in the study. Men who set type are , occupationally exposed- to hot ' metal fuincs and filings, which may contribute to the develop - -i tent of lung cancer, Dr. Ham mond said. The cooperating unioni were - selected, in part, for the exct-1- lent health ic-vnis iney nave maintained on their members through tnc years, Dr. Sc-lihoff . -- said. Mr. Powers's union has death records going back to 1K60, the pressmen's union has records sir.ee 1204- and the as bestos workers' union Iras rec ords dating back to its inception i;t 1912. Dr. Seiikoff said that in many cast.-, employers will participate in tho studies. Dr. Hammond estimated the . . ..ncer society's contribution to . study--which has indeter- -- n.inate scone and length--at about Si-million a year. In a speech last night at the society's annual dinner, Elliot L. Richardson, Secretary of Health, .
