Following on from the success of the 2016 IRMF meetings, the 1^st 2017 Ionising Radiation Metrology Forum, IRMF, was held at the Birchwood Centre, Warrington on the 7^th June 2017.

The IRMF is designed to give the Metrology sector the chance to share experiences across varying aspects of radiation measurement and testing.

In this session 51 delegates listened to varying topics which included: -

• Progress on the Portable Neutron Instrumentation Inter-comparison
• Overview of the status on a number of Radiation Metrology related National and International Standards
• Dynamic Testing of Radiation Detection and Monitoring Equipment which has been developed by DSTL in Alverstoke.
• Methods for activity measurement uncertainty minimisation in Waste Management & Decommissioning
• The measurement of Carbon-14 and Tritium in Air using novel techniques which includes the use of lasers.
• Gamma imaging and mapping using portable instrumentation

And finally

• Raising the question following the call for comments on the new Ionising Radiations Regulations in respect to the continued annual calibration of Radiation Detection and Monitoring Equipment

A number of lively and lengthy debates followed a number of presentations with a number of items generating further questions which a number of delegates have taken away with a view to responding to the group and the next meeting which will be held at the National Physical Laboratory in November.
