I.D.B. Holland Co-57 Flood Sources line offers the option of an outer inactive region to reduce hand exposure during routine calibration procedures where calibration fixtures or camera designs do not indicate source size. Active and inactive regions are easily identifiable. Standard configurations with minimal boarder area are also available when camera systems govern source dimensions. Each Co-57 Flood Source is provided in a durable shielded case for transport and storage to minimize external radiation levels.
