Word: Geiger Tube

Part of Speech: Noun

Definition: A Geiger tube is a special tool used to detect radiation. It is a part of a device called a Geiger counter, which measures ionizing radiation. The Geiger tube contains gas that can become ionized (which means it can carry an electric charge) when radiation passes through it. This ionization creates a small electric current, which the Geiger counter can measure and then indicate to the user, often with a sound or light.

Usage Instructions:

• Geiger tubes are commonly used in laboratories, nuclear power plants, and by safety professionals to measure radiation levels.
• When using a Geiger counter, you will point it at an area or object to check for radiation. The Geiger tube inside will detect any radiation and help ensure safety.

Example:

• "The scientist used a Geiger counter with a Geiger tube to check if the old building had any harmful radiation."

Advanced Usage:

• Geiger tubes can be calibrated to detect different types of radiation, such as alpha, beta, or gamma rays. This is useful in scientific research and safety monitoring.

Word Variants:

• Geiger Counter: This is the entire device that contains the Geiger tube and is used for measuring radiation.
• Ionization Chamber: A general term for a device that detects ionizing radiation, which includes a Geiger tube.

Different Meaning:

While "Geiger tube" specifically refers to the device used in radiation detection, "Geiger" alone could refer to Hans Geiger, the physicist who invented the Geiger counter.

Synonyms:

• Radiation detector
• Ionization detector

Related Terms:

• Radiation: Energy that comes from a source and travels through space.
• Ionization: The process by which an atom or a molecule gains or loses an electric charge.

Idioms and Phrasal Verbs:

There are no specific idioms or phrasal verbs directly related to "Geiger tube," as it is a technical term. However, you might hear phrases like "check for radiation" or "monitor radiation levels" in discussions about safety or scientific procedures.

Summary:

A Geiger tube is an important component in detecting and measuring radiation.
