What’s a dosimeter?

Dosimeters measure exposure to hazards like radiation and noise in various environments, including manufacturing, medical, and food production. Personal and long-range dosimeters are used to ensure safe exposure levels for workers.

Dosimeters are electronic devices that are used to assess the degree of exposure an individual experiences when working in a potentially hazardous environment. Devices of this type are used in places where people deal with hazardous waste or radioactive substances, or where there is regular exposure to high levels of noise. The function of the dosimeter is to measure the rate of exposure and make sure that no one is subjected to what is considered a dangerous level.

In general, the concept of dosimetry concerns the measurement of the effects of exposure to various types and levels of each type of stimulus. An acoustic dosimeter is often useful in manufacturing situations where heavy machinery is used to produce goods. Data retrieved from the device can help management identify the most effective types of hearing protection for employees working near machines. The devices are also useful for measuring sound levels in other environments, such as concerts, airport terminals, and any other area where people are subject to loud noise.

A radiation dosimeter is used to identify the presence and intensity of any type of ionizing radiation within a given environment. Some examples of ionizing radiation include gamma rays, alpha and beta rays, and X-rays which are commonly used in medical settings. Often, people who work in places where there is constant exposure to one of these types of rays wear a small dosimeter all the time. The tool helps them know the current exposure rate at any time during the working day, thus making sure that the exposure rate stays within safe limits.

It is also possible to use a dosimeter in a food production environment. Here, the device will measure the level of food irradiation occurring in the facility, effectively maintaining acceptable levels of radiation exposure for both the food and the employees working in the facility. Long-range dosimeters are commonly used in this context, allowing radiation levels to be monitored throughout the facility.

Both personal and long-range dosimeters are in common use today. In some settings, such as in a manufacturing plant, the use of both types of electronic dosimeter is not uncommon. This allows you to get individual readings from employees as they move through the facility, as well as an overall reading for the general area. Both forms of data are useful for keeping workers safe and relatively free from any overexposure hazards.
