电磁波作用于机体主要产生热效应及非热效应。热效应主要发生在血流量少的机体部位,因为在这些部位血液的自然冷却作用相应减少。首先是眼睛,尤其是眼睛的晶状体,当辐射密度在80mW/cm~2作用时间较长时,即可导致白内障。其次是人的生殖腺和脑,它们对加热很敏感。 Electromagnetic waves acting on the body mainly produce thermal effects and non-thermal effects. The thermal effects occur mainly in body parts where blood flow is low, as the natural cooling of the blood in these areas is correspondingly reduced. The first is the eye, especially the lens of the eye, which can cause cataracts when the radiation intensity is longer than 80 mW / cm2. Followed by the human gonads and brain, they are very sensitive to heating.
