radio activity

Was the screening an Xray machine that is used on HGVs that help detect unauthorised  people hiding in the vehicles

Sorry I cannot give any answers to you all but Border Force could not give any results.Perhaps border force at Portsmouth could resolve this .  

Sorry but I thought you were given a good explanation? 

Perhaps the explanation was in relation to the reason they were stopped in the first place (quote: we were told our outfit or our selves were showing signs of radio activity.The lady was very good at her explanation.) and not an explanation of the findings? 

Only guessing, I'd rather have a full tale as well!

I think I have may have sussed it,it picked up some one who actually got their Pioneer fitted radio to work. 

I wouldn’t worry unduly if you were stopped, especially if there were others who were stopped behind you. Everything is radioactive in varying degrees and the detection instruments have to discriminate between background radiation and radiation levels that constitute a risk to national security. The instruments are very sensitive and need regular calibration since drift over time is a real problem. It’s likely the detection instrument was due, or overdue, for calibration and hence the higher than expected number of vehicles being stopped. It’s unlikely the static instrument could tell which radionuclide was responsible for the alarm, it likely a more sophisticated hand held device would be required to determine that.

Perhaps he'd been doing a relief run to Chernobyl.
