Sensitivity of organs to radiations
The calculation of biological doses takes also into account the sensitivity of different body parts through ‘tissue weighting factors' . For example, reproductive organs are thought to be 20 times more sensitive than skin. These coefficients allow to estimate how toxic an exposure is by converting the amount of energy absorbed (in grays) deposited locally in body parts to an effective dose (in sieverts) that concerns the whole body.
