1. INTRODUCTION
 Radiation chemistry is a branch of chemistry that
studies chemical transformations in materials
exposed to high-energy radiation.

5. UNIVERSITY OF AGRICULTURE FAISALABAD – UAF
2. PRINCIPLE AND WORKING
 The sample material is bombarded with high energy charged particles such as
(a) X-Rays, Gamma Rays High energy particles including electrons (Beta rays) or helium
nucleus(Alpha rays). Irradiation results in the ionization of material
A + hv1—» (A+ )* + (e~)* + hv2
.

MEDICINAL APPLICATIONS
 Radiation Therapy RT
 Commonly used to treat cancer by
damaging the DNA of cancerous tissue
leading to cellular death.

DIAGNOSTIC RADIOLOGY
Diagnostic radiology refers to the field of medicine that
uses non-invasive imaging scans to diagnose a patient.
 Radiography (X-rays)
 Computed Tomography (CT) Scans
 Magnetic Resonance Imaging (MRI) Scans
X-ray images
Computed Tomography (CT) Scan

8. INDUSTRIAL APPLICATIONS
UNIVERSITY OF AGRICULTURE FAISALABAD – UAF
 Electron beam irradiation treatment
of textiles materials

FOOD IRRADIATION
.
 This is the process of exposing food to ionizing radiation to destroy
microorganisms, bacteria, viruses, or insects that might be present in the food

STERILIZATION
 Radiation sterilization of a product means destruction of all viable
organisms present on that product(mainly microorganisms) by using
ionizing radiation

11. UNIVERSITY OF AGRICULTURE FAISALABAD – UAF
ENVIRONMENTAL APPLICATIONS
 Extensive work has been carried out for utilizing electron-beam technology
for environmental remediation.
Sterilization of Drinking Water

12. ENVIRONMENTAL APPLICATIONS
UNIVERSITY OF AGRICULTURE FAISALABAD – UAF Flue gas Treatment

AGRICULTURAL APPLICATIONS
 Mutation
 To induce genetic alterations in order to
improve crop variates and mutation breeding.
 To create crop varieties that are more disease
resistant
Two sources of the mutant in
progeny, left shows that the
mutant originated from direct
transmission from irradiated
seeds, right shows that the
mutant was formed through
genomic instability.
