Chapter 25.4, Problem 26LC

Interpretation Introduction

Interpretation: To state the three detection devices.

Concept Introduction: Some devices are used to detect radiation. The radiations that are emitted by the radioisotopes are called ionizing radiations.

Answer to Problem 26LC

The three devices use different sources to detect the radiation.

Explanation of Solution

The three devices that are used to detect radiation are as follows:

• Geiger counter
• Scintillation counters
• Film badges

In the Geiger counter device, the gas-filled metallic tube is used to detect the radiation.

In the Scintillation counters, the phosphor-coated surface is used to detect the radiation.

In the film badges, the photographic film along with the black-light proof paper is used to detect the radiation.

Conclusion

Thus, the devices and their sources for detecting radiation are mentioned above.
