Labeling
The device is labeled in accordance with Sections30192.1 of the California Radiation Control Regulations (equivalent to 10 CFR 32.51),10 CFR 20.1901,and 10 CFR 20.1904.
Prototype Testing :
The eletrical actuator until have been tested by the manufacturer for effects of sever vibration and at temperatures up to 100°C. Continues vibration in accordance with the Class 4 test of ANSI ,NBS Handbook NO.126 was carried out on a shake table.The unit was held at 60°C for several weeks .The shutter was operated in excess of 100,000 open-close cycles.The manufacturer states that these vibration and temperature tese results are also applicable to the pneumatic actuator units ,as the design of the two devices is identical with the exception of the actuator .The ANSI classification assigned by the manufication of the Amersham source and materials of construction.
External radiation levels:
The radiation profiles with the shutter open and closed were taken with a Lanseverk R Meter .With the sourece in the OFF postion ,the measured radiation is substantially less than 100 mrem/hr at 92.5px .At 125px it is substantially less than 5 mrem/hr.
Quality assurance and control :
There is a quality inspection of all incoming components as well as those manufactured by NDC .An independent check is made by a quality assurance inspector who verifies proper construction of each device using specific tests prior to shipment.
