process of acquiring an image through the means of exposing radiation (x-ray)
radiography
most commonly known as the x-ray film
radiograph
is the finished product form radiography

forms of radiation used
x-ray, soundwaves, radiofrequency waves, gamma rays
common radiation foudn what
sunlight - visible light; ultraviolet
cellular and entwork signals - microwave
how x ray happened (history)
x-rays were not developed but rather it was discovered by accident
who discovered x-rays
wilhelm conrad roentgen
how was x ray discovered
roentgen was experimenting with a type of crookes tube on November 8,1895 at wurzburg university in germany
when was x ray disocvered
novemeber 8, 1895
where was x-ray discovered
wurzburg university in germany
WHAT WERE THE MATERIALS INVOLVED?
Cathode Rays, Crookes Tube, Barium Platinocyanide
NAMING OF THE RADIATION
Initially called X-light, X means unknown
x meaning in xray
unknown
Injuries occuring due to
receiving a certain dose of
radiation.
Radiation Injury
Radiation Protection
Time, Shielding, Distance
most effective readiation protection
distance
ALARA
➢ Keeping radiation “As low as
reasonably achievable.”
Removes low energy radiation.
Radiation Filtration
Restricts useful radiation beams
to specific parts
Radiation Collimation
common radiation usage
medical field; everyday use; scientfic stsudeis
Roentgen darkened his lab and completely enclosed
his Crookes tube with black photographic paper to
better visualize the Cathode Rays in the tube. During
the experiment, a barium platinocyanide was lying
on a bench meters away from the crookes tube.
After the experiment, no visible light escaped but
the barium platinocyanide glowed.
during the expereiment
