What are three examples of field survey instruments?

The correct answer, which includes the Geiger counter, scintillation counter, and ionization chamber, identifies three well-known types of field survey instruments used in radiation safety to detect and measure ionizing radiation.

A Geiger counter is widely used for its ease of use and ability to detect different types of radiation, including alpha, beta, and gamma particles. It produces audible clicks or visual signals in response to radiation, making it an efficient tool for quickly assessing radiation levels in various environments, especially in field conditions.

Scintillation counters use materials that emit light (scintillate) when they absorb ionizing radiation. These devices are highly sensitive and are often used in medical applications, research laboratories, and environmental monitoring. Their ability to measure low levels of radiation makes them particularly valuable for detailed surveys where detection of small radiation amounts is necessary.

The ionization chamber measures radiation by collecting ions produced by the radiation within a gas. It can accurately determine exposure levels, making it useful in both diagnostic settings and radiation safety assessments. It's commonly employed for area surveys and personal monitoring.

In contrast, the other options include instruments that serve specific purposes but do not fit the category of field survey instruments as clearly. Film badges and thermoluminescent dosimeters (
