Nuclear
Waste Screening
Using the AXIS-3D® Industrial Scanner
The Problem
Amersham Plc is one of the world’s leading suppliers of nuclear
medicines and image enhancing materials for use in medical treatment
and diagnostic procedures. In disposing of their own and customer’s
waste, Amersham wishes to meet and often to exceed the strict regulatory
requirements for disposal of the potentially hazardous materials through
their waste and decommissioning department. For their low level radioactive
contaminated materials the normal methods of disposal require that
a range of non-compliant items (such as sharps, heavy metals, fluids,
etc) are identified and separated from their waste material and treated
separately.
The comprehensive screening required to identify the possible presence
of non-compliant items within waste is a critical activity within
the highly regulated process of radioactive waste disposal. The current
method of manual screening each and every sack is an obvious and effective
solution, but it is also costly and inefficient since the screener
has to be able to identify even the smallest watch battery in a large
sack of general waste. Coupled with the additional health risks to
the operator (sacks may contain hidden sharps), Amersham required
a simple method for remote screening of sealed waste bags to identify
the presence and position of non-compliant items prior to their clearance
for the next stage in the disposal process.
