OBJECTIVES -The goal of this study was to examine whether exposure to electric or magnetic fields is related to cancer. METHODS -The study cohort consisted of 5088 men who had worked for at least one year between 1920 and 1991 for any of eight participating companies which produce and distribute hydroelectric power in Norway. The occupational exposure of these workers included extremely low-frequency electromagnetic field s. Incident cancer cases identified from the Cancer Registry of Norway were analyzed on the basis of the standardized incidence ratio with the Norwegian male population as reference . RESULTS -The incidence of cancer was close to unity for the cohort. The standardized incidence ratio for lymphoma was below unity, whereas those for leukemia and brain tumors were similar to those expected . Calculated cumulative exposure to electric or magnetic fields was not associated with the incidence of leukemia or brain tumors, but an exces s of malignant melanoma was shown for the highest category of magneti c field exposure. An analysis of combined possible exposure to oils containing polychlorinated biphenyls and exposures to magnetic fields or possible exposure to electric sparks gave standardized incidence ratios of 265 and 280, respectively, for the higher exposure category. CONCLUSIONS -These result s do not support the assumption of a possible associ ation between exposure to electromagnetic fields and leukemia and brain tumors . The possible association between exposure to polychlorinated biphenyls or magnetic fields and risk of malignant melanoma should be further evaluated in future studies.KEY TERMSbrain tumor, cohort , electromagnetic fields, leukemia, malignant melanoma , occupational exposure.

A cohort of 1687 registered captains and mates from a Norwegian census in 1970 was followed until 1987 using a historical prospective design. By matching the data from the census to the Norwegian Cancer Registry, 104 cases of cancer were found. A control group of 376 was chosen among non‐cases at baseline (1970). Information about the seamen's work on different ships was obtained from the National Register of Norwegian Seamen. The material was analysed using multivariate logistic regression. An increased risk of developing cancer was found in the group of seamen who had been working on tankers, especially oil tankers (OR = 6.47,95%CI: 1.14, 7.24). The increased risk was found to be significantly correlated to working as mate on these tankers (OR = 6.95, 95%CI: 3.70, 13.04), whereas working as captain showed a much lower risk (OR = 1.42, 95%CI: 0.64, 3.15). Chemical exposure is the major factor separating tankers from other ships. Mates are exposed to chemicals while captains are not. The study indicates the presence of several carcinogenic agents on these tankers.
