Hi: I am working with a group responsible for testing marine radar equipment, retrieved from vessels involved in accidents. This group tests the equipment and then store it while accident/police investigations are carried out (this can take > 12 months). One of the surveyors raised concerns about the potential for release of hazardous substances (specifically barium products) from the equipment while in storage. Does anyone know or can you point me in the direction of where to find out (1) what products, if any, can be released from stored radar equipment and (2) what the correct storage conditions are for this equipment? Appreciate any help. Thanks.

HI Elle
Are you are referring to complete Radar installations internal and external?
The Antenna is designed to work in all conditions so storage should not present a problem.(Weatherproof and lots of room)
The main electronics equipment should be stored in dry conditions, it usually comes in custom built containers to prevent damage from impact or ingress of moisture. May be difficult for second hand equipment.

The only nasty I know of is Beryllium Oxide which the main power devices may be coated with.

I stand to be corrected if wrong. Hop this is of use

You need to be specific re which type of /form of 'Barium' you are dealing with as 'Barium [56]'[Ba131 / Ba 140] is also radioactive via gamma rays

Try NRPB [as they were] for more info

Hi again Elle
Modern Radar that uses multi chip module technology may have (BST) Barium Strontium Titanate components or (BMT) Barium Manganese Tantalate components.
The equipment in question should pose little risk of exposure under storage conditions, providing the equipment is not damaged or involved in a fire.
Just a thought; You could ask if they have the freight storage boxes. A very long shot I know.

Good luck Alan N
