Beta radiation ~ Stream of electrons (unit negative charge). Beta positive radiation is when a positron is emitted rather than an electron.
Gamma radiation ~ Electromagnetic radiation of very short wavelength = high photon energy.
Gamma radiation ~ Electromagnetic radiation of very short wavelength = high photon energy.

Explanation:
-Gamma rays: Gamma rays are a form of electromagnetic radiation. They have the shortest wavelengths and highest frequencies in the electromagnetic spectrum. Gamma rays are produced by nuclear reactions and radioactive decay. They are highly penetrating and can be harmful to living organisms.
-X-rays: X-rays are also a form of electromagnetic radiation, but they have longer wavelengths and lower frequencies than gamma rays. X-rays are commonly used in medical imaging to visualize the internal structures of the body. They can also penetrate materials and are used in various industrial applications.
-Neutrons: Neutrons are subatomic particles that have no electrical charge. They are found in the nucleus of an atom along with protons. Neutrons are involved in nuclear reactions and are used in various scientific and industrial applications.
-Electrons: Electrons are subatomic particles that have a negative electrical charge. They orbit around the nucleus of an atom and are involved in chemical reactions. Electrons can also be accelerated to high energies and used in various technological applications, such as electron microscopy and particle accelerators.
Answer:
The correct answer is option D: electrons and electromagnetic radiation of wavelengths shorter than X-rays.
- Gamma rays and X-rays are both forms of electromagnetic radiation. Gamma rays have shorter wavelengths and higher frequencies than X-rays.
- Electrons are subatomic particles that have a negative charge and can behave as both particles and waves. When accelerated to high energies, electrons can emit electromagnetic radiation with wavelengths shorter than X-rays.
- This type of electromagnetic radiation is commonly referred to as "gamma radiation" or "gamma rays," even though it is produced by electrons rather than by atomic nuclei.
- Therefore, the statement "-rays are electrons and electromagnetic radiation of wavelengths shorter than X-rays" is the correct description.
