Methods: Between 2016 and 2021, a retrospective open cohort study was carried out with workers who were employed from 08\/31\/1956 to 12\/31\/2016 based on data collected at the company and in official institutions. Standardized mortality ratios (SMR) were calculated by sex, age and calendar period of cancers grouped according to type, risk factor and organ system in two analyses: in the external analysis, the mortality of the study population was compared with that of the general population of the city of S\u00e3o Paulo; In the internal analysis, the mortality of the monitored subgroup was compared with that of the subgroup not monitored for gamma and X radiation.  Results: The external mortality analysis showed SMR=0.224 (95%CI 0.208\u20130.240) and the healthy worker effect, while the internal mortality analysis showed SMR=0.685 (95%CI 0.618\u20130.758).  Conclusion: This study showed lower cancer mortality among exposed workers when compared to mortality in the general population and the healthy worker effect. Among workers monitored for gamma and X radiation, cancer mortality was lower when compared to those not monitored.<\/jats:p>","DOI":"10.1590\/1980-549720240011","type":"journal-article","created":{"date-parts":[[2024,3,18]],"date-time":"2024-03-18T06:15:24Z","timestamp":1710742524000},"source":"Crossref","is-referenced-by-count":0,"title":["Cancer
