We described how Viridian can save time and money with in situ techniques for characterisation, while improving safety to personnel using remote deployment to reach inaccessible areas and those places where access is restricted because of high activity.  It is always a pleasure to discuss technical issues with technical experts in the sector and these guys have been in the business a long time. To quote their website, “Cavendish Nuclear – people who innovate to deliver...

The two nuclear characterisation instruments developed in the REACH project have somewhat different deployment requirements; the ViridiScope is relatively light laser sampling head that requires physical contact to take samples, while the Createc N-Visage system is significantly heavier, but does not require physical contact. However, they both target characterisation with remote deployment. ViridiScope has been reduced in size to permit it to be deployed in pipes and voids as small as 15 cm...

When a nuclear facility is shut down, a painstaking process is initiated to dismantle the facility and clean up any remaining nuclear material so it no longer poses a threat to safety. This process requires a lot of sampling to determine the radiation levels contained within various materials at a site and traditional methods are very labour- and time-intensive. Viridian Consultants – experts in instrumentation solutions for the nuclear sector – saw an opportunity to improve this...

ViridiScreen is a very sensitive and, importantly, robust alpha detection system, which uses the measurement of photons derived from the interaction of alpha particles with nitrogen in the air to determine the gross alpha activity on a surface. We are delighted that Sellafield Ltd has chosen to trial the use of ViridiScreen for a particularly challenging application on site. Kym and John have trained a member of Sellafield staff to use ViridiScreen in preparation for the work.

Viridian Consultants has been working closely with Lynton Lasers Ltd, a British-based company specialising in the manufacturer and supply of aesthetic, surgical and conservation lasers. By turning the laser light through 90^o we are able to use ViridiScope to take samples down pipes and round corners where access is difficult with conventional sampling tools.
