Anyone got an answer for this little problem?  (apologies if it has already
been posted)


At the end of the specification document DGT state:

Radiation emission:   <= 0.18 uSV/h   - which equals 1.5mSv/year

This exceeds the maximum allowable level  by 50%... and we can see the
device is lead shielded - so this is what gets through the lead, apparently.

Maximum acceptable dose for the public from any man made facility: 1
mSv/year
