X-RAY
BY
LUCAS CARTER
THE HISTORY
Wilhelm Roentgen is the man who is credited for being the
first to accidentally discover x rays and later naming them
The discovery was made while he was working on effects
of cathode rays in 1895
He was experimenting with passing electric current
through gases at low pressure. But one day on November
8, 1895,during his observation of the rays in a dark room
the emission of the rays caused an illumination on a
barium platinocyanide covered screen and caused it to
become fluorescent
HISTORY
After this discovered he used the x-rays using
photographic plate to capture the image of various
objects that had different thicknesses to them and
placed them in the path of the rays

WHAT ARE X- RAYS
(x-ray) X ray: electromagnetic radiation of short
wavelength produced when high-speed electrons
strike a solid target. These can be altered to be used
in soft materials such as tissue or in more hard like
bones and metals
FIELDS THAT USE
X-RAYS
The two fields of x-rays include
• use in medical field-
• Use in industrial field-
MEDICAL USES
X-rays are widely used in medicine to reveal the
architecture of the bone and other soft tissues and to
find out any abnormality in the form of fracture,
growth of tumor etc. It is also used in dental imaging.
MEDICAL X-RAY MACHINES
• x-ray radiography (to find orthopedic damage,
tumors, pneumonias, foreign objects, etc);
• mammography1 (to image the internal structures of
breasts)
• CT (computed tomography)2 (to produce crosssectional images of the body)
• fluoroscopy3 (to dynamically visualize the body for
example to see where to remove plaque from
coronary arteries or where to place stents to keep
those arteries open)
• radiation therapy in cancer treatment
INDUSTRIAL USE
X-rays reveal structural information about the material
through which it passes or falls over. It can therefore be
used to detect structural deficits or cracks in metal objects
that are likely to be missed by the human eye. It is also
used to reveal stress related changes in building materials
for bridges and aircrafts.
The use of X-rays in airports to examine for the presence of
dangerous weapons or bombs is a routine practice. The
cargo is also examined similarly for illegal transit of goods.
Some backscatter X-ray scanners can scan much
larger objects, such as trucks and containers. This
scan is much faster than a physical search, and
could potentially allow a larger percentage of
shipping to be checked for smuggled items,
weapons, drugs, or people
These type of x-rays are also used in smaller scale in
airports in security with machines like AIT84 Body
Scanner & Castscope
REVIEW
• With Wilhelm Roentgens accidental discovery of the
x-ray(electromagnetic radiation) it has played in
important roll in the advancement in medical as
well as industrial technology
• with the new discovery inventions like the CT scan
and the full body scan have been developed help
to save people both from injury and stopping
terrorism
NOTES
• Medical use mammograms for soft tissue and ct for
deep bone
