卫生标准限量值(1)连续波1日8h暴露的平均功率密度为50μW/cm~2;小于或大于8h暴露的平均功率密度以:Pd=400/t计算(即日剂量不超过400μW·h/cm~2)。(2)脉冲波1日8h平均功率密度为25μW/cm~2;小于或大于8h暴露的平均功率密度以:Pd=200/t计算(即日剂量不超过200μW·h/cm~2)。(3)肢体局部辐射1日8h暴露的平均功率密度为500μW/cm~2;小于或大于8h暴露的平均功率密度以:Pd=4000/t计算(即日剂量不超过40O0μW·h/cm~2)。(4)短时间暴露最高功率密度的限制当需要在大于1mw/cm~2辐射强度的环境中工作时,除按日
Hygienic standard limit value (1) The average power density of exposed continuous wave at 8h on the 1st is 50μW / cm ~ 2 and the average power density at or below 8h is calculated by Pd = 400 / t (ie the daily dose does not exceed 400μW · h / cm ~ 2). (2) The average power density of pulse wave at 8h on the 1st is 25μW / cm ~ 2; the average power density at or below 8h is calculated as Pd = 200 / t (ie the daily dosage does not exceed 200μW · h / cm ~ 2). (3) The average power densities exposed to local body radiation on day 8 were 500μW / cm ~ 2; the average power densities exposed to less than or greater than 8h were calculated as Pd = 4000 / t (ie daily dose not exceeding 40O0μW · h / cm ~ 2 ). (4) Restrictions on Maximum Power Density for Short-Term Exposure When working in environments with a radiant intensity greater than 1 mW / cm 2,
