Centro de Documentacion de Fundación MAPFRE - Radon and thoron daughter working levels in British coalmines

Notes: Sumario: Shift-average radon and thoron daughter working levels have been measured at 11 collieries in the U.K. Levels were low (generally less than 20 milli-working levels) compared with those typical of uranium mines. The possible influences of various factors on the level of activity were examined, but a correlation was found only with ventilation distances from pit bottom to the sampling siteRelated records: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 3, 1984 ; p. 315-320Materia / lugar / evento: Higiene industrial Contaminantes químicos Radón Control de la contaminación Muestreos Minas de carbón Gran Bretaña Otros autores: Crawford, N.P.
