Infra - red radiation
	According to the biological activity infra-red rays are divided into short-wave with the wave range from 760 up to 1400 nanometers and long-wave with the wave range from 1500 up to 25000 nanometers

Слайд 14





Absorption of IR rays by the skin is determined by the wave length 
Rays with the length from 1500 to 3000 nm are absorbed by superficial skin layer 
Rays with the length 1000 nm passes through the epidermis, shorter IR waves reach the subcutaneous fat

Слайд 16





The most marked unfavorable influence of IR radiation is observed in industrial conditions 
	In glass-blowers and other workers, contacting with intensive flows of IR radiations, there is decrease in electric sensitivity of eyes, weakening of the conditionally reflex vascular reaction. Infra-red radiation if the wave-length is less than 1400 nanometers leads to serious changes in cornea as cataract
