characteristic x-rays rays

X-rays are generated by quick brake of fast moving electrons in the e mass
with high atomic number. Due to short wavelength x-rays x
are able to scan
human body in dependence to biochemical composition of organs and d by analysing
of them we can see internal body morphology.
X-rays used in diagnostic imaging are produced using a device called an x-ray x
tube
(a a special evacuated container in lead case).
Spiral filament of tungsten is heated by passing an electrical current c
through it. At
sufficiently high temperature, some of the electrons in the filament have enough
thermal energy to escape their attraction to the filaments metal atoms and to boil of
to form a cloud.
