Show fc'Msffea Guidelines New mine radial ion cn-trol cn-trol fyuldelines have been completed by the Joint Committee on Atomic Kn-et'fv, Kn-et'fv, and texts of two 1 i M' I" I standards are now available. The N7.1 Sub-eomimillee Sub-eomimillee has Invited eomnieiit s on them before the final versions are sub-milted sub-milted to the USA .Slan-dards .Slan-dards Institute. The mini" regulations follow earlier standards imposed as an emeroney measure when an alarm was sounded over a hiph incidence of lung cancer among uranium miners. The report drafts deal with problems that loomed loom-ed large at the Joint GommiHee hearings. One, designated NJ7.1 A, titled "Air Sampling for Radon Daughters" focuses on sani'tiling method?: of evaluating ev-aluating exposures, and the effectiveness of control con-trol techniques. The other, N7.1C, concerns "Record Keeping in Mines" and !: Intended to provide guidance guid-ance to 1he employer for sytematic generation and regeneration of exposure records. Nuclear Industry magazine maga-zine this month quoted Rep. Melvin Price, of the Joint Committee on Atomic Atom-ic Energy, as describing the original N7.1 standard of lOoO as the result of the work of "very capable, far-sighted men." He believes be-lieves it has done much to help our mining states show steady improvement over the years in reducing reduc-ing radon levels in mines. Rep. Price added he believed be-lieved the most significant and immediate contribution contribu-tion to proper implementation implemen-tation and enforcement of the new standard will be. the recommended guidelines guide-lines nnd operating techniques tech-niques which the N7.1 Subcommittee is preparing. |
