Disk Sources

Introduction

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.

Po-210 Disk Source

Introduction

The Po-210 disk source is designed for use as an alpha reference source. Po-210 is chemically plated on to the surface of a silver disk that is mounted at the bottom of the well of a Plexiglas® disk. The completed sources is unsealed. This source is offered in two sizes: 1.0” x 0.125” and 2.0” x 0.125”.

All Po-210 disk sources have an uncertainty of ± 20% of the labeled activity.

Not available for calibration.
If a sealed source is required, Po-210 is also available as a laminated disk source with an Al/Mylar window.
