Understanding Film Badge Dosimeters

What is the primary chemical used in photographic films for detecting radiation?

• Silver bromide

• Gold chloride

• Copper sulfate

• Iron oxide

What is the initial color of the photographic film before exposure?

• Black

• White

• Light gray

• Dark gray

How is the film badge dosimeter typically worn?

• Around the neck

• In the pocket

• On the wrist

• On the chest

What is the purpose of the aluminum and lead filters in a film badge dosimeter?

• To protect the film from light

• To reduce the weight of the dosimeter

• To distinguish between types of radiation

• To enhance the film's sensitivity

What does it indicate if the film in a dosimeter turns dark?

• The film was exposed to light

• The user was exposed to radiation

• The dosimeter is faulty

• The user is safe from radiation

Why is alpha radiation usually not detected by film badge dosimeters?

• Alpha particles are too fast

• Alpha particles are too large

• Alpha particles cannot penetrate the filters

• Alpha particles are not harmful

What happens to the film when exposed to both beta and gamma radiation?

• Only one area turns dark

• The entire film turns dark

• The film becomes transparent

• The film remains light gray

What is the main advantage of using film badge dosimeters?

• They are reusable

• They are lightweight and portable

• They are inexpensive

• They provide instant results

Who primarily uses film badge dosimeters?

• Nuclear plant workers

• Photographers

• Medical patients

• Astronauts

What is the role of the lab in the use of film badge dosimeters?

• To manufacture the dosimeters

• To analyze the film for radiation exposure

• To repair damaged dosimeters

• To distribute the dosimeters
