Paper Abstract

Optical radiation hazard evaluation for broad band sources must usually be performed by a highly trained specialist with the use of sophisticated instrumentation. While some direct reading ultraviolet radiation hazard evaluation instruments have been developed, no similar instrumentation for retinal hazard evaluation is available. The general principles of optical radiation hazard evaluation are reviewed along with the quantities, units, and measurement systems used. A new prototype ultraviolet radiation hazard monitor utilizing a spectrograph and spectral weighting mechanical mask, which provides a direct reading of the effective irradiance according to the ACGIH Threshold Limit Values, has recently been developed. The sensitivity for this prototype instrument is 10-7 W/cm2 (effective irradiance) with an uncertainty of less than 30%.
