Deployment and Retrieval
The overall radiation mapping service based on the device consists of six individual steps. Step 1 involves placing the device inside the given contaminated area with a known position and orientation. This can be achieved in a number of ways including deployment by crane, robot, by an operator or (as in most cases) by a remotely operated manipulator arm. The device can be orientated either upright or upside down. Once the device has been placed in position, Step 2 involves leaving the device in-situ to enable dose uptake. Once the device has been left in-situ and has achieved a suitable dose uptake (between 2 and 5,000 rads), Step 3 involves removing the device from the contaminated area. Once clearance has been given, Step 4 involves removing the radiation sensitive core from within the collimation device, ensuring that it has not rotated or moved during the deployment period.
