Texas Industrial Radiography Gamma Practice Test

Which human senses can detect Gamma and X-Radiation?

1. Sight and Touch

2. Smell and Taste

3. Sight and Hearing

4. None of the above

The correct answer is: None of the above

Gamma and X-radiation are forms of ionizing radiation that cannot be detected by human senses. Unlike visible light, which can be seen, or sound waves that can be heard, gamma and X-rays do not produce any sensory feedback that we can perceive. As a result, individuals cannot rely on sight, touch, smell, taste, or hearing to detect these types of radiation. This is why the correct answer is that none of the provided human senses can detect gamma and X-radiation. Detection requires specialized equipment, such as Geiger counters or dosimeters, to measure and indicate the presence of these forms of radiation.
