物理因素的职业危害主要指的是些什么?物体的振动-工业噪声(可听声),超声与次声(非可听声);机械振动-有局部振动和全身振动;非电离辐射-高频电磁场与微波,紫外与红外线,激光等;电离辐射-X线,r射线等;异常的气象条件-高低温,高低气压等。本文试图介绍常见的数种物理因素职业危害,以引起人们的重视及警觉。当今世界,噪声是最重要的公害之一。噪声,空气,水三大污染是当代污染最重要的攻关课题。美、英、德、法、日等国把噪声的危害放在首位。据报导,美国普通中等城市,每二十人中就有一人因噪声所致听力损害;美国有三千八百万人接触高中强度的噪声;美国国际飞机场噪声由于起飞降落频繁,噪声级高,据报道其周围的儿童生长发育受到一定的影响,飞机场附近居住人群,精神病发病率高……。因此,世界上有千百万人受到噪声公害
Occupational hazards of physical factors mainly refer to what? Object vibration - Industrial noise (audible sound), ultrasound and infrasound (not audible sound); Mechanical vibration - Local vibration and whole body vibration; Non-ionizing radiation - High Frequency electromagnetic fields and microwaves, ultraviolet and infrared, laser, etc .; ionizing radiation -X ray, r ray, etc .; abnormal meteorological conditions - high and low temperature, high and low pressure. This article attempts to introduce several common occupational hazards of physical factors to arouse people’s attention and vigilance. In today’s world, noise is one of the most important public hazards. Noise, air and water pollution are the most important contemporary pollution topics. The United States, Britain, Germany, France, Japan and other countries put the harm of noise in the first place. It is reported that one in every 20 people in the U.S. average middle-level cities suffers from noise-induced hearing impairment; 38 million people in the United States have exposure to high school-level noise; and the U.S. International Airport noise is high due to frequent take-off and landing and high noise levels , It is reported that the growth and development of children around them are affected to some extent. The population living in the vicinity of the airport has a high incidence of psychosis. As a result, millions of people in the world are exposed to noise pollution
