LEE251C - EPA-high detection efficiency, low background configuration, HPGe gamma radiation detector

The RFT has ended, you cannot answer the invitation.

 

Overview

 

The Environmental Protection Agency is at the front line of environmental protection and policing.  We ensure that Ireland's environment is protected, and we monitor changes in environmental trends to detect early warning signs of neglect or deterioration.

 

Protecting our environment is a huge responsibility, and we work with a number of organisations that carry out specific environmental functions.  As of August 2014, we are also responsible for ensuring that the people of Ireland are protected from the harmful effects of radiation.

 

The EPA is an independent public body established under the Environmental Protection Agency Act, 1992. The other main instruments from which we derive our mandate are the Waste Management Act, 1996, and the Protection of the Environment Act, 2003 and Radiological Protection (Miscellaneous Provisions) Act 2014.

 

This call for tender relates to the purchase of a high purity germanium detector designed to work in a low background passive shield equipped with anti-coincidence active shielding, to minimise minimum detectable activities across the gamma energy range <20keV to >2 MeV for the measurement of environmental samples in both Marinelli and planar sample geometries.

 

Tenders will be evaluated on both the basic fulfilment of a requirement, and accompanying justification for each presented solution.

 

 

 

This purchase will improve EPA’s capability for the characterisation of radionuclide concentrations in environmental samples. It focuses on increasing measurement sensitivity and sample throughput: to improve emergency response times for the measurement of artificial radionuclides, and minimum detectable levels of naturally occurring radioactive material. The chosen model will enable the establishment of a low background gamma spectrometry setup consistent with the efficient implementation of modern standards and recommendations for radiological monitoring, in combination with ongoing improvements to active and passive shielding.
