A how much you can to glow ?

 A how nany times is to do KT  test, or x ray  ,that not affect on a health bad? Would an affect radiation  is dangerous  , than an own disease? 

From an all  kinds od diagnosis are three: x raym fluorographym scintigraphy, and computer tomography are tied with dangerouse radiationm and  in spite of belief opinion a harmful effect on organism for otherkinds of researches are MRT, ultrasound are not proven. MRT  has based on a radiation of electer magnet waves, ultrasound on emission of mechanicaloscillation .And both are not habing relation to ionizing radiation.

Roentgenologic  rays are splitting molecules on based parts , thus under theirs effects are destroying membranes of vital cells, damaging keepers' foe genetical information as DNA, RNA .Thus a  hard roentgenologic radiation causing cells dead or damaging theirs by genetically code and mutation with a later  staying a reason for cancer rebirth, and in sex cells is rising deformities in a future generation. Ionizing radiation are harmful for organism tissues, which intensively updating or growing. And a first from a radiation suffering bone brain, where is forming cells of immunity in blood, skin and mucus membranes, and tissue of  fetus on pregnancy time. A most sensitive to radiation are children's, sp as level of metabolism and speed of cellular separation are higher, than in adult, children's are growing constantly, thus a doing theirs vulnerable before radiation.

But, roentgenologic methods as fluorography, x-ray, scintigraphy, and CT  are popular using in medicine.A few from us are putting under rays a x-ray apparatus by own initiatives, that to define percents for lungs damaging in coronavirus.But a most often on ray diagnosis prescribing your doctor.And you are in hospital to receive prescription on massage or for pool, but therapeutist prescribing you a  fluorography .And,  why this risk?And how to measure a harmful in x-ray and compare her with a which  a need such testing? 

A stats  , by a showing a harmful from x ray rating is an effective dose for radiation, she is measuring of mills or microsieverts as MSV, MSV. Before these dosages rating by special tables, where are stayed middle numbers. Now every moden x-ray apparatus or CT having dosimeter built-in , which  right after testing showing quantities for sieverts  by you received .Its depending from many factors as body size, which are radiated by a hardness of x-rays, distance from a ray tube and apparatus, on which testing done. A dose received in testing of one region is changing on 2 or more times , and thus a post-factum to calculate a how much radiation you are received, is just by approximately. And its better to discuss right away as staying in office as asking in doctor information is used, and how much is an effective dose of radiation received? And by a law, its all fixed in a note of accounting for dosage loads, which attaching to your ambulatory  card, of you are investigating at hospital, thus these numbers doctor putting in discharge .But , on the practise this is  not always having.
