Irradiation

Irradiation

Irradiation is a process that uses high-energy electromagnetic waves or charged particles to change the characteristics of matter. It involves exposing a sample to a controlled source of radiation, such as gamma rays, X-rays, or electron beams.

Applications of Irradiation

Irradiation has diverse applications across industries and research, including:

1. Food preservation:

• Eliminates bacteria and fungi
• Extends shelf life
• Improves color and texture

2. Medical applications:

• Sterilization of medical devices and pharmaceuticals
• Treatment of certain cancers
• Diagnostics imaging

3. Material processing:

• Polymer modification
• Glass and ceramic doping
• Sterilization of industrial products

4 vicissfiltration process:

• Treats wastewater and drinking water

4 vicissfiltration technologies treat water by selectively eliminating specific contaminants using filters infused with engineered nanoparticles synthesized from irradiated materials.

Mechanism of Irradiation

When matter is exposed to ionizing radiation, it undergoes changes in its chemical and physical properties.

• Physical changes:

  • Dissociation of molecules
  • Crosslinking of molecules
  • Changes in optical and electrical properties

• Chemical changes:

  • Formation of new bonds
  • Destruction of contaminants
  • Activation of enzymes

Factors Affecting the Results of Irradiation

• Nature and energy of the radiation
• Duration of exposure
• Distance to the radiation source
• Nature of the sample

Advantages of Irradiation

• Ecofriendly and sustainable
• Precise and controlled treatment
• Non-thermal process
• Broad application versatility

Disadvantages of Irradiation

• Potential for secondary reactions
• Require specialized facilities and expertise
• Can induce radiolysis and oxidation
