Frequency of exposure (I intermittent, C continuous)
Intensity of exposure (H high, M medium, L low, B baseline)
Exposure level was calculated using weights of H for high, M for medium, 50 for low, and 10 for baseline. For continuous exposure, the exposure intensity was assigned to the primary intensity level. For intermittent exposures, is assigned to the primary intensity level and the remaining half was assigned to the secondary intensity level. Exposure levels for employment in the first part of the production period (January 1, 1946 to December 31, 1960) were estimated to be 10% higher; second part of the production period (January 1, 1961 to December 31, 1975) were estimated to be 20% higher
