Gamma rays and x are useful when used in?

Medical Imaging:

- X-rays: X-rays are commonly used in medical imaging techniques like X-ray radiography, computed tomography (CT) scans, and fluoroscopy.

- Gamma rays: Gamma rays are used in certain nuclear medicine procedures, such as bone scans and some types of cancer imaging.

Cancer Treatment (Radiotherapy):

- Gamma rays: Gamma rays are often utilized in radiotherapy to target and destroy cancerous cells. This is done using devices called Gamma Knife or CyberKnife, which deliver precise doses of radiation to affected areas.

Food Preservation (Irradiation):

- Gamma rays are employed in food irradiation, a process that helps preserve food by eliminating microorganisms and extending its shelf life.

Industrial Radiography:

- Gamma rays and X-rays are used for non-destructive testing and inspection of materials, such as weld joints, castings, and composite structures, to detect internal defects.

Security Screening (X-ray Baggage Scanners):

- X-ray scanners are widely used at airports, customs, and other security checkpoints to inspect baggage and cargo for potential threats.

Astronomy and Space Exploration:

- Gamma rays are utilized in astronomy to study high-energy phenomena in the universe, such as black holes, neutron stars, and supernovae, through telescopes like the Fermi Gamma-ray Space Telescope.

Material Characterization:

- X-rays are employed in techniques like X-ray diffraction and X-ray fluorescence to analyze the crystal structure and elemental composition of materials.
