According to the Law of Bergonie and Tribondeau, which factor is NOT a main contributor to radiosensitivity?

The Law of Bergonie and Tribondeau outlines how the radiosensitivity of cells is influenced by certain biological factors. These include mitotic activity, maturity, and degree of specificity.

Mitotic activity refers to how frequently a cell is dividing; actively dividing cells are generally more sensitive to radiation. Maturity describes the developmental state of the cell; younger, less differentiated cells tend to be more radiosensitive. Degree of specificity relates to how specialized a cell is; less specialized cells are typically more susceptible to radiological damage.

Inherent filtration, on the other hand, pertains to the processes or materials that absorb or filter out ionizing radiation, which does not directly influence the biological response of the cells being irradiated. This factor does not fit within the biological considerations outlined in the Law of Bergonie and Tribondeau, making it the correct choice in this context.
