Report on a cancer cluster in an antenna ranges facility

A cancer cluster which occurred among young workers in an antenna ranges facility is reported. Five out of about 30 workers were diagnosed with cancer. The calculated odds ratio (OR) was 8.3 with confidence interval (CI 95%) of 2.3 to 19. Since this is a single cluster no definite conclusions can be drawn from it by itself, however together with other similar cases reported elsewhere it tends to indicate a severe cancer risk for groups of young people exposed repetitively and over years to non-ionizing radio-frequency radiation at levels limited only by the ICNIRP thermal limits.
