Model PMA1120 Analog UV Radiation Safety Sensor
Solar Lights Model PMA1120 Analog 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.
Solar Light’s Model PMA1120 Analog 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. 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 that 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.
