To ask Her Majesty's Government what blood analysis testing is carried out on members of the United Kingdom Armed Forces to detect and prevent genetic damage caused by radiation.

Members of the UK Armed Forces who are classified radiation workers undergo annual radiation medicals in accordance with the Ionising Radiation Regulations 1999. These medicals are conducted by appointed doctors, appointed by the Health and Safety Executive in accordance with the regulations. There is no requirement to undertake any routine blood testing during these medicals and the decision to order any investigations is left to the clinical judgment of the appointed doctor based on the individual case. No routine testing to detect and prevent genetic damage is undertaken because no validated test currently exists for the levels of exposure seen during normal operations.
