Field and clinical study of the occupational hazards of long-wave ultraviolet light from fluorescent BLB bulbs, and of noise level, on lightly clothed personnel in 55 New Jersey nightclubs, cabarets, and go-go bars. Maximum light energy was measured as 0.2 microwatts per square centimeter at 253.7 nanometers, 1.4 microwatts per square centimeter, and from less than 20 to 210 microwatts per square centimeter at 365 nanometers; noise levels ranged from 90 to 107 decibels. Clinical findings for inspection of the skin and eyes of hostesses and dancers are related to physiological characteristics including age, hair and skin color, and susceptibility to suntanning, and are correlated with work duration and weekly exposure time, and distance from and level of the lights. No significant clinical evidence of damage to eye or skin is found; however, interpositon of ordinary glass between the light source and the employee is suggested for reducing the potential eye and skin hazards from the light emitted in the erythemogenic frequencies without diminishing visual effects. Exposure time of customers to the light and noise is determined as insufficient to be hazardous.
