São aqui relatados os resultados do censo abreugráfico de 1984 de uma empresa de grande porte, isenta de riscos ocupacionais para o aparelho respiratório. Em 5,308 abreugrafias realizadas foram detectados 53 casos de anormalidades abreugráficas (1%), dos quais apenas 4 de tuberculose ativa. O rendimento foi de 0,75/1,000 abreugrafias. O custo médio de detecção de cada caso de tuberculose ativa foi de 256,32 ORTN (ao redor de 1.850 dólares). Foi também constatado um menor comparecimento de funcionários ao exame abreugráfico periódico, 1,6% de ausências em 1982 e 7,8% em 1984, causado provavelmente pelo crescente conhecimento leigo sobre radiações ionizantes, Os resultados são discutidos e é apresentada uma revisão sobre o emprego de exames radiológicos periódicos em saúde ocupacional.This paper reports on the results of the 1984 Minimal Mass Radiography (MMR) screening in a large company with no respiratory harzards are reported. Among 5,308 MMR there were 53(1%) abnormal findings with 4 cases of active pulmonary tuberculosis. The yield from screening was 0.75/1,000 MMR. The mean cost of diagnosing each active case of tuberculosis was around US$ 1,850. An increase in refusal rates to attend the screening, from 1.6% in 1982 to 7.8% in 1984, probably because of the increasing lay knowledge of radiation harzards, was also noted. The results are discussed with a short revision of ionizing radiations and the usefulness of X-ray screenings in occupational health.
