Sealed radioactive sources are available in a wide range of isotopes covering Alpha, Beta and Gamma emissions. These sources are exempt from USNRC and State licensing and present no special storage or disposal requirements.

Activities are selected to produce sufficient count-rate to check survey meters or conduct most nuclear science experiments in normal lab periods using standard Geiger Mueller counters or scintillation detectors, yet low enough so as not to present any radiation hazard.

Sources are available sealed in one inch diameter plastic discs, in a variety of test tube sizes, or as needle sources for use with cloud chambers. Laminated disk and credit card source are now available as NEW products.

Custom activities and packaging are available on special order.

Gamma source may be ordered calibrated for an additional fee.
