Hi all, bit of a strange one this but I have a client who manages what is basically a large warehouse holding equipment for the MOD.
They store a massive amount of army 'glow in the dark' watches which contain gaseous tritium light sources inside the watch.
Due to the amount stored on site is there anything the client needs to do in relation to certification/storage/management etc for these radioactive items?
I would not normally have considered this as an issue but the client actually mentioend it as a concern?
Any help would be gratfully apprichiated
Thanks
Chris

Chris I think you will find there is an exemption for these: Gaseous Tritium
Light Devices SI 1985 No 1047.

Radioactive Substances Act Guidance (RASAG)
Chapter 3 - Exemption Orders copy on the Environment Agency Website.
They are OK so long as they are properly stored etc.

Chris,
You could contact the Radiation Protection Advisers for the MOD for their advice. Google "DSTL Radiation Protection Services" for their contact details.

Your client does say he has "a massive amount of army 'glow in the dark' watches".
The exemption order does specify that the exemption from registration for storage is only good for up to 20 GBq.
It probably unlikely that he is exceeding that limit but it should be checked. As another responder says its worth checking with DSTL.
It might also be worth checking if he is storing other devices which might contain radioactive sources such as Smoke Detectors Again there are exemption orders but with an upper limit on activity

Just had another thought as I hit the post button.
You said your client manages the warehouse.
I do wonder that as he is not the owner if any of the Crown Exemptions might apply to the radioactive materials?

Chris,
You may also find that a lot of the watches do not contain tritium at all but are coated with luminescent paint instead. DSTL will be able to tell you or your friend how to spot the difference.
