Discovery
W.C. Roentgen confirmed a phenomenon that fluorescent
reaction is caused by unidentified light during a shield
cathode-ray tube using examination in Nov. 8th, 1895.
He named this unknown light X-ray and published the result
of his research in Dec. 8th, 1895. This thesis gave him
the first Novel prize for literature. |

Action of X-ray
1) Physical Reaction :
¿©±â, Ionization, Exothemic reaction, Fluorescent reaction
2) Chemical Reaction :
A fast electron, made by X-ray, can have chemical reaction
in case that there is ionization or ¿©±â.
3) Physical/Chemical
Reaction :
X-ray has photographic reaction as visible light does.
Therefore, it makes the internal structure of a body and
is used to measure by coloration reaction.
4) Biological Reaction :
X-ray can be the reason of aging hasten, genetic hindrance,
and so on because it has not only an acute reaction, such
as skin erythema, a ulcer, etc. But it also has ¸¸¹ß reaction,
so that can cause aging hasten, generic obstacles, etc.
It has been using for radiotherapy of malignant tumor. |

Generation of Damping X-ray
The origin of damping x-ray is the energy conversion
that is generated when rapid electronic ray abruptly decelerate
at target in anode of X-ray tube. X-ray tube is a vacuum
tube that has anode with target and cathode with filament,
creator of electron. When filming, high voltage is offered
between both poles. Peculiarly, target is consisted
of tungsten and has high atomic number, 74, and it can
resist high temperature due to its high melting point,
