Disk sources are designed for use as reference sources. Each source is constructed using a Plexiglas® disk and is offered in two sizes: 1.0” x 0.125” and 2.0” x 0.125”.
All disk sources have an uncertainty of ± 20% of the labeled activity unless calibrated (± 5%) for an additional cost.
|Alpha and beta sources cannot be calibrated.|
|Domestic and international U.S. NRC exempt quantity source orders with activities over 10 μCi MAY require lead shielding. If required, the lead shield will be added to your order.|
