Question

What is the primary purpose of the various attenuation filters located in the film badge?

1. remove low energy, x-rays, gamma rays & beta particles
2. determine whether the film exposed once or more than once
3. estimate the direction from which radiation was incident upon the film
4. permit dose measurement over wide range of energies

Answer 1

The primary purpose of the attenuation filters in the film badge is to allow accurate measurement of radiation exposure over a wide range of energies. These filters are made of materials that absorb different types of radiation.

Step-by-step explanation:

The primary purpose of the attenuation filters located in the film badge is to permit dose measurement over a wide range of energies. These filters are made of materials that absorb specific types of radiation, allowing the film badge to detect and measure the amount of radiation exposure accurately.

Attenuation refers to the process of reducing the intensity of radiation as it passes through a material. The filters in the film badge are designed to attenuate different types of radiation, such as alpha particles, beta particles, and gamma rays. Each type of filter is optimized to absorb a specific range of energies, allowing for accurate measurements across a wide range of radiation types and energies.

For example, a film badge may have a filter made of aluminum to absorb low-energy photons (X-rays) and a filter made of plastic to attenuate high-energy particles (such as beta particles). By using these different filters, the film badge can provide a comprehensive measurement of radiation exposure, regardless of the energy of the radiation.
