iPIX - Ultra Portable Gamma-Ray Imaging System

iPIX - Ultra Portable Gamma-Ray Imaging System

Description

iPIX is a unique gamma imager that quickly locates and identifies low level radioactive sources from a distance while estimating the dose rate at the measurement point in real time. It is the ideal tool to map a radioactive area before entering the zone, thus reducing the dose exposure (ALARA) during standard operation or decommissioning. iPIX is also the appropriate instrument to detect any suspicious radioactivity in security and safeguard applications, as well as for emergency situations such as Fukushima.

Technology

iPIX integrates the GAMPIX technology developed by the Atomic Energy Commission (CEA) in France. It is based on a 1 mm CdTe detector bonded to a pixilated CMOS chip – the Timepix sensor developed at the CERN research center – a coded mask and mini optical-camera.

The coded mask aperture allows for background noise subtraction by means of a technique called mask/anti-mask differentiation. This greatly contributes to the reduced size and weight of the gamma imager. The mask automatically rotates to the anti-mask position based on the measurement conditions (background and source activity).

The radioactivity mapping is automatically superimposed onto the visible image of the scene of interest.

Application

iPIX is a real-time ultra-portable gamma-ray imaging system mostly designed for in situ gamma measurements to locate radioactivity at nuclear sites. When planning for maintenance or decommissioning operations, it can be used to provide radiation intensity maps of the area. During radiological accidents, emergency situations, reactor outages or even routine area surveys where radiological conditions are subject to change (e.g., near piping), iPIX can help find radiological hot spot locations and quickly determine the boundaries of contaminated areas.

iPIX requires very little shielding while maintaining an excellent signal to noise ratio. This translates into a lightweight device (2.35 kg/5.5 lb) with a compact design (9 x 9 x 18.8 cm/3.5 x 3.5 x 7.4 in.) that can easily be deployed and transported in the field. The camera can be installed on a standard or motorized tripod that allows remote positioning of iPIX to focus on the area of interest.

MERCURAD - 3D Simulation Software for Dose Rate Calculation

MERCURAD - 3D Simulation Software for Dose Rate Calculation

Description

The MERCURAD software, with its powerful user interface that can display 3D scenes, offers a practical solution to meet the complex dose calculation requirements of health physics specialists, shielding calculation engineers, and staff involved with nuclear facility maintenance and nuclear installation dismantling projects.

The new MERCURAD software is built using the computation engines of the well known and tested MERCURE calculation code(1). It makes extensive use of a new graphical user interface, thus allowing very complex items to be easily defined and presented.
