5 Beneficial Uses of Radiation
1.
Radioisotopes allow us to date organic
objects, such as rock layers, fossils and
other artifacts.
• Carbon 14 (14C)
• Phosphorus 32 (32P)
Radioisotopes allow us to find leaks,
weak spots, and wear on metal pipes
and surfaces that rub together.
2.
Radiotracers allow us to see
pathways inside the body.
•
131I
can be used to see the
thyroid gland.
• 24Na and 59Fe allows us to see the
circulatory system.
• 32P allows us to see bones
3.
Radioimmunoassays detect very,
very small amounts of chemicals in
the body, such as pregnancy
hormones and early signs of cancers.
4.
MRI
Magnetic resonance imaging
Gives detailed images of internal
structures
5.
Radiation can be used to kill harmful
cells
• Kill bacteria in food
• Kill cancer cells
