Electron Beam Welding – HSE Consent Approval

Posted on by

In a slight deviation from the usual applications, Market Cross assisted two companies to achieve IRR17 Consent Approval for Electron Beam Welding (EBW) operations.

EBW acts like a high-powered X-ray generator. When the high-speed electrons strike the metal workpiece, their rapid deceleration releases penetrating ionising radiation known as Bremsstrahlung (or braking radiation). Following a full IRR17 assessment and implementation of recommendations, both companies received Consent from the HSE to carry out their operations.

Radiation Protection at Capenhurst Nuclear Facility

Posted on by

A Market Cross RPA visited the Capenhurst nuclear site today to discuss radiation protection matters with a number of operating companies, including the site operator Urenco.

The focus was on an upcoming project involving the installation of new cranes in one of the cylinder waste stores. Also discussed were the various methods to ensure doses to personnel were kept as low as reasonably practicable, including time management, shielding, proximity management and emergency arrangements.

Market Cross supports Family Science Day at Dorset Museum

Posted on by

Three Market Cross members travelled to Dorset Museum and Art Gallery in Dorchester to support Family Science Day on 16th March. We shared the beautiful Victorian hall with a number of innovative science related organisations, companies and community groups both local and national.

Our stand included modules representing different radiation related subjects, activities and handouts. Some very informative material was also kindly provided by the Society for Radiological Protection (SRP).

We encouraged as many people as we could to get involved in the wonderful natural world of natural and man-made radiation, while helping everyone to understand, and get into perspective, the risks of ionising radiation.

You need a very sensitive detector to see the radiation from a curling stone! But its there.

Market Cross Providing Support to State of the Art Security Inspections Project

Posted on by

Market Cross has been appointed as the RPA to provide the radiological systems necessary work safely with a new mobile security imaging technology. These mobile devices make use of the X-ray backscatter effect and produce an instantaneous image of the contents of containers, packages or anything the hand-held device can be brought in proximity to.

Market Cross also provided Critical Examinations of the mobile systems to characterise the operational and accidental dose-rates and to ensure the devices were in line with UK standards.

Market Cross Provides RPA support to Thorium Processing Project

Posted on by

Market Cross has been appointed by Baldwin Technology as the RPA to provide radiological and legal support for staff working on a thorium processing project in Slough. The process enables the addition of natural thorium to specialised lighting products which, in turn, enables the products to emit unique wavelengths within the ultraviolet part of the electromagnetic spectrum. The thorium also improves the integrity of the products, leading to a long operational life.
