Gamma Legacy Irradiator

Gemini have listened to our customers and designed a Legacy Irradiator that still possesses the key design features and build quality of our Gemini systems but allows the use of existing 3rd party Radioactive sources.

MECHANICAL FEATURES
•Proven Fail-Safe Shutter and Rotary Source Carousel design as used in our Gemini Irradiators in service for over 20 years.

•Proven fail-safe Am-241 Exposure Unit as used on our latest Gemini Irradiators.

•Multi ring lead and Tungsten shutter as used on our current Gemini Irradiators.

•Solid Tungsten Source Carousel minimizes dose interference from adjacent source positions

•Side entry loading of Radioactive Sources to eliminate awkward top entry using ladders and overhead crane.

•Specially designed Source Transfer Flask supplied with Irradiator, compatible with Gemini SSV.

MODULAR DESIGN
•Enables the assembly of Irradiator inside a cell and later be dis-assembled and moved to new cell in the future.

•Easy transport of components into small existing cells.

•Design optimized by use of Tungsten in key areas to keep overall Irradiator size to minimum.

•Enables precision alignment of internal features as its built.

IRRADIATOR CAPACITY
•Shielding calculated to safely store 6 TBq Co-60 Source.

•Internal carousel designed to hold 8 radioactive sources plus a blank 9th position.

•Front mounted Am-241 Exposure Unit designed to shield 100 GBq Am-241.

•Surface Dose-Rate less than 2.5 uSv/hr at Irradiator casing.

•We can be flexible with design and in process of designing Cs-137 Irradiator for customers that don’t require Co-60.

CUSTOMER BENEFITS

•Designed to accommodate existing Mainance source holders.

•Allows equipment to be purchased without the expensive cost of new sources until required.

•No high disposal cost of old sources until no longer useful in terms of dose-rate.

•Gemini can supply & load new sources on an individual basis as and when they are each due for replacement.

•Takes away worries over known weaknesses with old Irradiator design.

•No harsh movement of Sources in Irradiator means that lifetime of capsule is increased.

•Sources securely housed in Source carousel.

•New Irradiator will comply with BS EN standards unlike current old Irradiators.
