Слайд 2

Solar radiation is integral flow of radiation, emitting by Sun
From

the physical point of view solar energy is a flow of electromagnetic radiation characterized by a various wave-length

Слайд 3

Solar radiation is a great medical and prophylactic factor
It influences

on all physiological processes in the organism, changing metabolism, general tone and efficiency

Слайд 4

Reactions of organisms depend on:
the type of radiation
the length

of electromagnetic waves
the absorption of these waves by tissues

Слайд 5

Ultra-violet part of the solar spectrum
it is a wave flow in

the range from 200 up to 400 nanometers

Слайд 6

General biological influence of ultra-violet rays
local changes in the colloidal

state of cellular and tissue proteins
Образование cleavage product of protein molecules such as hystamin, choline
influence on protein, fat, carbohydrate and mineral metabolism
increase in the organism protection

Слайд 7

Ultra-violet radiation with the wave range:
from 400 up to 320

nanometers – range A, UV-A
from 320 up to 275 nanometers – range B, UV-B
from 275 up to 180 nanometers – range C, UV-C

Слайд 8

Specific biological influence of ultra-violet rays typical of a certain wave

range

range A, UV-A – leads to erythematous-suntan influence
range B, UV-B – antirachitic and low bactericidal influence
range C, UV-C – causes a damaging influence on a biological tissue, skin, eyes

Слайд 9

UV-A
The mechanism of origination of ultra-violet erythema is connected with

the vasodilating effect of histamine and the histamine-like substances formed under ultra-violet radiation.

Слайд 10

UV-B
Revealed in participation of UV radiation of this range in

the synthesis of vitamin D
The result of UV-irradiation on the skin is the transformation of 7-dehydrocholesterol in vitamin D3

Слайд 11

UV-C
Under the influence of natural ultra-violet irradiating of a bactericidal

spectrum sanation of the atmosphere, water, soil takes place

Слайд 12

Visible part of the solar spectrum
The visible part of the

solar spectrum is a wave range from 400 up to 760 nanometers
The special hygienic value of light is its influence on the vision function

Слайд 13

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
