Question

Which is the cause of damage referred to as relative biological effectiveness?

• A. High temperature
• B. Low temperature
• C. Pollution
• D. Radiation

Answer 1

The correct option is D

Radiation

The correct option is D.

The explanation for the correct option :

1. The relative biological effectiveness is referred to the ratio of two different amounts of radiation required for getting the same biological results.
2. As radiations have a great hazardous impact on biological components, it creates greater damage to the biological system.
3. Effectiveness may depend on the ratios of ions.

The explanation for the incorrect options:

Option A:

1. The high temperature is may caused due to high radiation from the sun.
2. But as the ionization radiation from the sun does not have much effect on relative biological effectiveness, High temperature does not show an impact of it.

Option B:

1. The low temperature does not have radiation.
2. Hence, Low temperatures do not show an impact on the relative biological effectiveness.

Option C:

1. Pollution is referred to the contamination of the surrounding environment and altering of its characteristics.
2. Pollution can also cause hazardous damage but it does not show an impact on the relative biological effectiveness.

Final answer: Radiation is the main cause of damage referred to as relative biological effectiveness.
