Description
Alpha Disk Sources
Alpha disk sources are designed for use as reference sources in laboratories, radiation protection, training and education, and security. Each source is manufactured by chemically plating radioactive material onto a silver disk mounted in Plexiglas®. Available in Po-210 with activities of 0.05 or 0.1 µCi and two disk sizes: 0.125 x 1.0 inches (3.2 x 25.4 mm) or 0.125 x 2.0 inches (3.2 x 50.8 mm). Ideal for performing functional checks on gamma counters, spectrometers, and radiation protection probes. Useful for educational demonstrations of radioactive decay, half-life, energy spectra, and radiation interactions. Suitable for functional checks of portable security devices and emergency exercises. Activities comply with U.S. NRC Exempt Quantity limits. Unsealed sources with ±20% maximum activity deviation.
