Which instrument is used to measure exposure rate?

The effective instrument for measuring exposure rate is a survey meter. Survey meters are specifically designed to measure the ionizing radiation levels in the environment, providing real-time data on the exposure rate of radiation. They can be used to assess radiation levels in various situations and are capable of indicating the amount of radiation present over a specified time period.

Survey meters typically have the ability to measure different types of radiation and convert that information into exposure rate readings, which are expressed in units like roentgens per hour (R/h) or microsieverts per hour (µSv/h). This makes them particularly useful for monitoring areas for potential radiation hazards and ensuring safety in environments where radiation is present.

While other instruments, such as Geiger counters, dosimeters, and ionization chambers, play important roles in radiation detection and measurement, they are tailored for different functions. Geiger counters are useful for detecting and counting individual ionizing events but may not provide direct exposure rate readings. Dosimeters are designed to measure accumulated dose over time and are typically used for personal radiation monitoring rather than continuous exposure rate tracking. Ionization chambers, while capable of measuring exposure rates, are often utilized in more controlled environments due to their design, which might not provide immediate feedback like a survey meter
