Radiation Protection Today Spring 2024 Issue 6 | Page 13

I present a selection of case studies from those I have encountered over the years to illustrate the types of problems that need to be dealt with in a timely manner , and with sensitivity .
• Fluoroscopic “ oncology ” Several decades ago we had an enthusiastic radiologist who regularly generated significant erythema ( reddening of the skin ) during his diagnostic screening sessions . Fortunately , technology and education encouraged him to consider both his dose rates and screening times !
• What rectal dose ? A junior colleague in the Nuclear Medicine department was required to monitor rectal dose during a radioactive seed implant procedure in the cervix . Bringing a high dose rate observation to the oncologist he was politely told to “ turn down the sensitivity until the measurement is acceptable ”. Needless to say , some words with the oncologist were required .
• Free magic money Our managers are always looking for extra cash . This is understandable given historical and present funding of the NHS . Our hospital was offered £ 5,000 a year to agree to the placement of a mobile phone mast on a tower next to a large and busy maternity department . Discussion with the National Radiological Protection Board ( NRPB as it was then ) and my own radiofrequency exposure calculations at ward level indicated that , on contemporary guidelines , there was not expected to be an overexposure issue . However , I pointed out to my hospital manager that one foetal abnormality on the unit would swiftly absorb any financial gain and cause a lot of bother . Nowadays , of course , no one worries about potential foetal exposure from mobile phones , which are ubiquitous throughout our wards !
• With hindsight The radiology department undertaking early MRI scans at another hospital in Wales rang to ask if I could talk to one of their patients over the phone . The patient was put on the line and was obviously a little distressed . She explained she ' d recently had an MRI scan , and subsequently found she was pregnant . In those days , first trimester scanning was not encouraged , so I had to think on my feet . I promised to get back to her within 48 hours with some guidance .
On this and many other occasions I was grateful I was a member of SRP . The Society ' s compact organisation with its topic groups and mentors provides invaluable access to a large number of experts who I have always found ready to rapidly assist in these and other situations .
My recommendations to younger members are to firmly embrace the available opportunities within the Society , volunteer for topic groups and committees , and acquire access to the wider expert network that is so readily available .
Do not be daunted by asking your peers what may seem a silly question ; you may be surprised how happy they will be to help .
