IonSens® 208 provides effective and reliable monitoring of
complex or solid items, permitting the categorization of the
material as either low level waste (LLW) or suitable for free
release. This enables operators to re-use or dispose of the
material in the most efficient and cost-effective manner. The
IonSens® 208 would normally be used by plant operators or
decommissioning teams as part of their quality plan to confirm that
material is suitable for free release.
At present, alpha-contaminated material is monitored using
techniques which are sensitive to alpha particles directly. Due to
the short range of alpha particles in air, these detectors need to
be close to the potential contamination source, to achieve
consistent results. This is a severely limiting factor when
attempting to monitor all exposed surfaces of complex items.
IonSens® 208 overcomes these limitations by remote detection of the
ions produced by alpha particle interactions in the air around the
entire item. Thus a single measurement is sensitive to
contamination located on all exposed surfaces of an item. This
provides an operator with an immediate cost effective solution to
the classification of a wide variety of complex and solid items
prior to final disposal.
Operational features:
- Accurate measurement of the exposed surfaces of complex items
such as process equipment and bent pipe work for alpha
contamination.
- Accurate measurement of the external surfaces of solid items
such as bricks and ingots for alpha contamination.
- Short measurement times for complex items.
- Classification of material as free release or LLW.
- Well proven, non-intrusive measurement technique.
- Accommodates wide range of item sizes.
- Automatic background and standardisation measurements performed
to maintain confidence in system performance.
- Measurement service option provided by a highly trained Babcock
team.Can be adapted for automated feed.
