Explanation of "Geiger Counter"

Definition:
A geiger counter is a device used to measure ionizing radiation, which is a type of energy that can come from radioactive materials. It helps people detect and measure the amount of radiation in the environment.

Usage Instructions:
  • How it works: A geiger counter has a special tube inside it that detects radiation. When radiation enters the tube, it creates small electrical pulses that the device counts and displays as numbers or clicks.
  • When to use it: People use geiger counters in places where radiation might be present, such as in nuclear power plants, hospitals (for X-rays), and areas affected by nuclear accidents.
Example:
  • "The scientist used a geiger counter to check if the area around the old factory was safe to enter."
Advanced Usage:
  • In scientific research, geiger counters are often used to monitor radiation levels in experiments or to ensure safety in environments where radioactive materials are handled.
Word Variants:
  • Geiger (referring to Hans Geiger, the inventor)
  • Counter (a device that counts or measures)
Different Meanings:
  • In this context, "counter" generally refers to a device that counts or measures something. However, "counter" can also mean a surface in a kitchen where you prepare food.
Synonyms:
  • Radiation detector
  • Radiation meter
Idioms and Phrasal Verbs:
  • While there are no specific idioms or phrasal verbs related directly to "geiger counter," you might hear phrases like:
    • "On the radar," which means something is being monitored or considered (not directly related to radiation but can imply awareness of a situation).
Related Terms:
  • Radiation: Energy emitted from substances like radioactive materials.
  • Ionizing Radiation: A type of radiation that has enough energy to remove tightly bound electrons from atoms, which can potentially cause harm to living things.
Noun
  1. counter tube that detects ionizing radiations
