Somehwere in the dim and distant past someone raised the thorny issue of chest x-rays for sports divers medicals. Whilst in civvie street they are no longer routinely required, in military circles there has been some confusion. At a recent (sports med related) meeting the issue was discussed and I have it from a reliable source that the following is current advice for divers: D/SG(MedPol) 350/7/4/ dated 20 Oct 98 In essence: All service personnel wishing to undertake sports diving must have had a normal chest x-ray within 5yrs of commencing dive training. Further x-rays are not required unless clinically indicated. Having asked an Occupational Health (OH) wallah why even this requirement is stipulated I was told that there were concerns, amongst the mil diving experts, that the chest x-rays were an essential means of reducing risks to divers, given the causes of diving related deaths. The OH Doc kinda told me 'If you knew the main causes of diving related deaths you wouldnt want to go in the water without a clear x-ray!'
