As a general rule, the pregnancy of an exposed professional does not imply her withdrawal from the work but it is necessary to revise its conditions to comply with the regulations in force.

According to the regulations on prevention services relating to the application of measures to encourage improvements in the health and safety at work of pregnant workers and workers that have recently given birth or are breastfeeding, the worker may not carry out activities that involve a risk of exposure to ionising radiation when there may exist a danger to her safety, her health or that of the child or foetus in accordance with the conclusions of a risks assessment.

According to the Regulation on Health Protection against Ionising Radiation, since a woman informs of her condition, the protection of the foetus must be comparable to that of the rest of the population. Thus, the equivalent dose for the foetus must be as low as reasonably possible so that it is unlikely to exceed 1 mSv, at least from the reporting of her condition until the end of the pregnancy.

The organisations responsible for assessing working conditions and providing specific advice on matters of radiological protection are the Radiological Protection Services (RPSs) and the Radiological Protection Technical Units (RPTUs) specifically authorised by the Spanish Nuclear Safety Council and that work in close collaboration with the relevant Occupational Risks Prevention Service (ORPS) and the director or supervisor of the facility.
