Radio sensitivity is a function of the metabolic state of the tissue being irradiated.

1. Physical factors which affect radio sensitivity:

1. Linear energy transfer

2. Relative biological effectiveness

3. Fractionation and protraction

2. Biological factors:

1. Oxygen effect

2. Age

3. Sex (females are less radiosensitive)

Law of Bergonie and Tribondeau is not the factors affecting the radiosensitivity. It is the increase in tissue response to radiation with increase in mitotic actvity of cell. "X-rays are more effective on cells which have a greater reproductive activity."
