Film Badge

Film badges are commonly used in industries that involve the handling of radioactive materials. These badges are designed to accurately measure and monitor the amount of radiation exposure received by individuals working in these industries. By wearing film badges, workers can ensure they are not exceeding safe radiation exposure limits and take necessary precautions.

Key Takeaways:

Film badges are used to measure radiation exposure in industries working with radioactive materials.
They provide an accurate measurement of radiation levels and help ensure workers’ safety.
Wearing film badges is crucial to monitoring radiation exposure and preventing overexposure.

**Film badges** consist of a small piece of photographic film that is encased in plastic and placed inside a holder or badge. The film is sensitive to **ionizing radiation** and will darken when exposed to such radiation. The amount of darkening on the film indicates the level of radiation exposure received by the individual wearing the badge.

**Each film badge has a unique identification number** assigned to a specific individual. This allows for accurate tracking and monitoring of radiation exposure over time. The badges are usually worn on the front or collar area of the person’s clothing, as this provides a closer approximation of the radiation exposure to vital organs.

**Film badges provide a passive form of radiation monitoring**. Unlike active dosimeters, which provide real-time data on radiation levels, film badges need to be collected and sent to a laboratory for analysis. The film is carefully developed, and the level of darkening is measured to determine the radiation exposure level. Once analyzed, the results are recorded and sent back to the individual and their employer.

**Interesting Fact**: The concept of the film badge dates back to the early 1900s when radiographers noticed their hands were becoming burned and discolored due to radiation exposure.

Function and Importance of Film Badges

Film badges play a crucial role in ensuring the safety of workers in industries that involve radioactive materials. Here are the key functions and importance of film badges:

**Accurate Radiation Measurement**: Film badges utilize photographic film, which is highly sensitive to ionizing radiation. This allows for precise measurement of radiation exposure levels.
**Monitoring Worker Safety**: By wearing film badges, individuals can track their radiation exposure levels and ensure they are not exceeding safe limits. This helps prevent long-term health issues associated with overexposure to radiation.
**Compliance with Regulations**: Many industries that handle radioactive materials are required by law to monitor and record radiation exposure levels of their workers. Film badges provide a reliable method of compliance with these regulations.

Types of Film Badges

There are various types of film badges available, each designed for specific purposes. Here are three commonly used types of film badges:

Badge Type	Features
