DCF security arrangements 5 www.redbooklive.comwww.redbooklive.com [version 6 February 2016] ……… and liaise with CTSO volume 2: approved products and suppliers, part 4: security protection products, section 5: physical security protection of buildings and other facilities the source is protected by a layer of ‘onion skins’ each conforming to specific security criteria i.e. irradiator, facility door, access doors, etc.
6
Protecting laboratories 6 Consider activity & nature of radioisotopes: high levels (<0.5 GBq) beta / gammas in life sciences are less radiotoxic than a few kBq of alphas (e.g. Po-210) quantity of waste generated in terms of public perception of threat (dirty bomb) – bags of P-32 waste present a low health risk but a significant collateral threat life sciences: the quantity of waste generated in terms of public perception of threat (dirty bomb) – bags of P-32 waste present a low health risk but a significant collateral threat accessibility of labs to students / public – DCF is a closed site but Central Campus labs have higher footfall.

DCF ion beam 8 5 MV ion beam accelerator to be supplemented by a 2.5 MV accelerator with two overlapping beam lines = 7.5 MV
9
Currently beam lines for low-energy corrosion 9 5 MV ion beam accelerator for radiochemistry and corrosion studies Current situation 3 mm metallic discs with metallic composition mostly known irradiated in an enclosed chamber mix of prompt and short lived beta / gamma radioisotopes rapidly diminishing dose rate – monitoring program for access to chamber hall and safe keeping of discs prior to release discs undamaged by irradiation so far as friability concerned, thus closed sources decay storage then off-site transfer to customers when disc composition is known the radioisotope mix or ‘fingerprint’ is predictable source accountancy procedures can be linked to the longest lived radioisotope which can then be tracked through an accountancy system source i.d. then relates to the metallic disc radioisotopes & activities and to a print out of the ‘fingerprint’ Environment Agency (closed source) permit conditions are met – everything is known Regulations for Safe Transport IAEA SSR-6 conditions are met – everything is known
10
2 lines for corrosion studies = headache 10 5 MV + 2.5 MV convergent ion beams for high-energy deposition corrosion studies 3 mm metallic discs with metallic composition mostly known irradiated in an enclosed chamber mix of prompt and short lived beta / gamma radioisotopes rapidly diminishing dose rate – monitoring program for access to chamber hall and safe keeping of discs prior to release discs are damaged by irradiation and friable decisions required high irradiation conditions could cause formation of short lived gaseous isotopes – is ventilation of the chamber required friable = open sources (licensing) discs significantly ‘hotter’ – does this effect storage and transport other handover issues common with previous slide has consignee a licence to receive who at consignee’s institute gives permission? – audit trail for UoM: 3 sites, (DCF), North Campus & South Campus – who has authority, who is responsible, how to track between departments, do departments have permission to receive and up to what limits = complex accountancy

12 Managing the permit – how? But managing the site inventory is achieved by routing all purchases through the Radiation Safety Unit
13
13 Managing the sources – currently The system Purchase request to Radiation Safety Unit RSU orders and receives source (or agrees other arrangements) RSU delivers source and issues stock holding and waste disposal record sheets User creates own accountancy methodology Record sheets summarised and returns to RSU each month Disadvantages (the system is adequate…but) No consensus of approach Difficult to compile and manipulate University data Had one accountancy system that was impossible to follow…no sustainability Isn’t obviously explicable to Environment Agency inspector Don’t trust decay calculation Real time observation not possible System can be by-passed – sanctions? Absent key staff = loss of data collection / compilation Permit requirements Source accountancy records kept and available at all times
