Health and Medicine
Diagnostic- nuclear medicine, X-rays, 1-131 for thyroid
cancer treatment, radiotracers in liver and Kidney function tests.
Therapeutic (radiation from Co-60 for cancer treatment
Sterilization Hospital equipment, especially plastic syringes that
would be damaged if heated
Industry
· Power
generation: Nuclear Fission Reactors for electricity, Navy ships and submarines
· To detect
leaking pipes: A small amount of radiotracer is injected into the pipe. It is
then detected with a Geiger counter (GM) counter above ground.
· Thickness
of the paper can be controlled by measuring how much beta radiation passes
through the paper to a GM
Research
· X-ray
diffraction for molecular structure - e.g. DNA structure.
· Isotopic tracers
(e.g. C-14, N -15 to study photosynthesis and nitrogen uptake).
· Isotopic
labeling (e.g. P-32, N 15, DNA electrophoresis)
· Improvement
of Food Crops; host plant resistance, development of crop varieties
· Insect Pest Control
The most effective control is Click
· Food
preservation; shelf life extension of fresh fruits & vegetables
· In the
measurement of soil moisture content, fertilizer uptake and erosion rates
· Control
of Insect Pests and Pathogens
· Genetic
manipulation of the pest and pathogens
· Refractory
to Plasmodium for malaria control
· Sterile
Insect Techniques
· Export of
Pest free Products
·
phytosanitary
treatment has useful application in making/ export of pest and disease
free products and shelf life prolongation. Irradiation
for control of quarantine and disease-transmitting pests which will be controlled by Clcik here
·
Sterile
Insect Techniques (SIT)
· SIT: to
sterilize overwhelming numbers of male insects for mating with wild females
resulting in suppression and eradication of the same species in the target
