Question

Relative Biological effectiveness (RBE) usually refers to damage caused by

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

Answer 1

The correct option is A Radiation

In radiobiology, the relative biological effectiveness (RBE) is the ratio of biological effectiveness of one type of ionizing radiation relative to another, given the same amount of absorbed energy. Different types of radiation have different biological effectiveness mainly because they transfer their energy to the tissue in different ways. The relative biological effectiveness varies depending on the particles, energies involved, and which biological effects are deemed relevant.

So, the correct answer is 'Radiation'.
