Nuclear techniques for the control of insect pests and pathogens

1.      Research
2.      Environment, Biology, Agriculture
3.      Health and Medicine
4.      Industry and Homes
5.      Power Generation

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 areas and Click here
