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