LSDISK01

For single gamma sources of >5 uCi, the LSD01 Lead Shield simplifies shipping problems and offers ultra-safe storage of sources.

LSDISK50

With a wall thickness of 0.5'', this container is suitable for higher activity gamma sources. Holds up to 20 discs. Outside Dimensions: h= 3.6 x 2.25", Interior Dimensions: h= 2.65 X 1.25", 0.5" thick, approximately 4.6 lbs weight, painted exterior.

NEEDLE SOURCES

Needle sources are used to generate a point source of radiation inside cloud chambers for demonstrating alpha and beta radiation tracks. Three different types of isotopes are offered, a pure alpha emitter, a pure beta emitter and a combined alpha /beta emitter.

NS-Po-210	0.01 µCi (alpha emitter)
NS-Sr-90	0.01 µCi (beta emitter)
NS-Pb-10	0.01 µCi (alpha/beta emitter)

TUBE AND ROD SOURCES

Exempt quantity gamma sources encapsulated in standard size test tubes or rods for use with well type radiation detectors. These sources are uncalibrated and of nominal activity. The isotope is deposited as a point source in the bottom of the tube and is then sealed with epoxy. Size must be stipulated: Tube Source 13x100mm, Rods 0.375” or 0.5”
