Combined dementia, Alzheimer’s, Parkinson’s and motor neuron disease ERR denotes Excess Relative Rate
A pooled analysis of the nuclear power plant workers, industrial radiographers, and medical radiation workers consisted of 367,722 after removing overlapping workers. The ERR at 100 mGy (95% CI) was 0.30 (0.08, 0.56).
