When used with our Model PMA2100 Dual-Input Data Logging Radiometer, Solar Light’s Model PMA2120 Digital UV Radiation Safety Sensor indicates how long a worker may remain at the measured position before reaching the threshold limit value (TLV) proposed by the American Conference of Governmental Industrial Hygienists (ACGIH) published guidelines. If desired, the instantaneous effective irradiance can be displayed in µW/cm2. The radiation can be integrated over time and the dose in mJ/cm2 can be shown on the Radiometer’s LCD display. The angular response of the PMA2120 sensor is cosine corrected, and suitable for measurements of diffuse radiation or radiation from extended sources.
The TLV exposure dose has been chosen by the ACGIH as one that can be tolerated, even if repeated every work day, without causing any long term effects. The TLV for occupational exposure takes into consideration the risks of acute and chronic injury to both an eye and skin. The eye is the most radiation sensitive organ, and therefore the dose causes no eye damage is the maximum allowable radiation dose. Actinic ultraviolet radiation (UVB and UVC) is strongly absorbed by cornea and conjunctiva. Overexposure of these tissues cause keratoconjunctivitis, commonly referred to as welder’s flash or arc-eye.
