RPI Service History
In the late 1950s the United Kingdom Atomic Energy Authority established a research site at Winfrith in Dorset. Since the 1960s, building A56 at Winfrith has been used to calibrate radiation monitoring equipment.
Prior to 1984 the calibration system consisted of sources, pneumatically raised and suspended in a ‘flight-tube’. The instrument under test was placed on the table, at a distance that had to be manually calculated.
A new calibration system was installed. It was controlled by a BBC microcomputer and featured:
In November 1990 the department was the first in the UK to achieved NAMAS (now UKAS) accreditation for the calibration of gamma doserate meters.
The calibration control system was completely redesigned and rebuilt. The industry leading design expanded the features to include:
•Windows based program
•on-screen live video (Colour)
•industry standard compatibility
•certificate generation with preview
In 1997 the whole department relocated to refurbished building, A56 at Winfrith.
RPI Services achieved UKAS accreditation for the Calypso™ surface contamination calibration system.
Today we employ 9 RPI experts and undertake over 5000 annual calibrations for some 80 clients in the UK and abroad.
