beta ray
Definition
- Noun:
- Beta ray: A stream of beta particles (high-energy, high-speed electrons or positrons) emitted by certain types of radioactive atomic nuclei during radioactive decay. Beta rays are a form of ionizing radiation.
Usage Examples
- Noun:
- The scientist used a Geiger counter to detect the beta rays emitted by the sample.
- Shielding for beta rays often requires materials like plastic or aluminum, rather than thick lead.
Advanced Usage
- "Beta-ray emission": The process by which a nucleus releases a beta particle.
- The isotope's decay is characterized by beta-ray emission.
- "Beta-ray spectrum": The distribution of energies among the beta particles emitted from a source.
- Analyzing the beta-ray spectrum helps identify the radioactive isotope.
Variants and Related Words
- Beta particle (n): The actual high-speed electron or positron emitted, constituting the "ray."
- A beta particle has a single negative or positive charge.
- Beta decay (n): The radioactive process that produces beta particles/rays.
- Carbon-14 undergoes beta decay to become nitrogen-14.
- Beta radiation (n): Synonymous with "beta rays," referring to the phenomenon.
- The lab technician wore protective gear to minimize exposure to beta radiation.
Synonyms
- Beta radiation: Often used interchangeably with "beta ray."
- Beta-particle emission: Describes the same physical phenomenon.
Related Phrases
- "Penetrating power of beta rays": A phrase describing how far beta rays can travel through matter.
- The experiment demonstrated the limited penetrating power of beta rays compared to gamma rays.
- "Beta-ray detector": A device, such as a Geiger-Müller tube, used to sense beta radiation.
- They calibrated the beta-ray detector before beginning the measurement.
Noun
-
radiation of beta particles during radioactive decay
