On the 16th June, James Murphy (a IRS Technical Officer) and I were tasked to go and complete a Mobile survey at Veterinary hospital in Ormskirk. The Mobile that we were told to survey was named AMX II which from first glance we thought would be a mobile II (Fluoroscopy) but when we investigated we found that the job paperwork was for commissioning a Radiographic Mobile. When we arrived we found that the kit was a AMX radiographic tube but the tube itself was 34 years old! We were both shocked and amazed that a tube had such a long life. If only all tubes were as robust!
When we got started on the survey we found that the controls were very basic only two dials one for KV and another for mAs(as you can see in picture) and two exposure switches, one on the mobile itself and another on small remote.
I found the mobile to be very different to the equipment we usually survey. The setting controls were very basic, but the exposure controls took a bit to get use to. There were two buttons you had to press to expose, a small trigger under the remote to prep and a button on top to expose. When we exposed we also found that there was a very large difference from the kV set and the kV monitored example being when we set 100kV we would monitor 80kV output.
The area that the mobile was very strange as well, it was kept below the hospital in a basement with the mobile, a lead screen and a few other pieces of kit and on either side of the room, there were stairs. Every so often a Veterinarian would bring down a dog to be weighed on a scale in the corner of the room, but by 11am the vet hospital seem to quiet down with not as many animals being brought through and we were able to finish the survey.
Overall, it was an interesting and enlightening experience to see such a well worn piece of kit, complete the survey effectively, and to work with animals whilst doing so. It is not often that your job allows you to work with nature after all!
