Radiation Shields for Wands


Radiation Shields for Wands

These radiation shields friction fit on the open end of the Geiger Counter wand. Each shield helps to block radiation from reaching the internal GM tube inside the wand.


The shields are useful in performing nuclear tests and experiments.


The Screen shield is an open mesh nylon screen that allows all radiation including alpha to pass through. The paper shield blocks alpha radiation, while permitting beta and gamma radiation. The aluminum shield attenuates beta radiation and the lead shield attenuates gamma radiation. Shields may be purchased separately or in a set.

Radioactive Sources



Radioactive Sources

Sample radioactive sources for testing the functionality of a geiger counter. Safe, un calibrated solid sealed sources are fabricated by depositing a license exempt quantity of activity in the well of a 1-inch diameter (25mm) by 1/8-inch thick (3mm) plastic disk. After drying, the well is filled with an epoxy material; sealing the radioactivity inside the source. Contains ±20% of the stated activity and are routinely compared to calibrated reference standards. Each disk is identified by radio nuclide, amount of activity, serial number and calibration date. The words "Caution - Radioactive Material" appear on the label of each source.


These radioactive sources are dropped shipped from separate location.


Pb-210 Needle Cloud Chamber Source Contains Pb-210 < 0.01 µCi

Geiger Counter Apps : Geiger Bot & iGeiger



Geiger Bot is a companion app for Geiger counters, providing you with a toolkit for recording, analyzing, and sharing Geiger counter data.
Geiger Counter Apps GeigerBot and iGeiger
Whether you need a numeric display for an old analog counter, graphing and extensive logging for even a digital counter, or online automated data sharing via Pachube, Geiger Bot can be of use.

Geiger Bot just works. As soon as you start up the app, Geiger Bot will get to work without any configuration necessary. This is done using adaptive signal processing and your device's microphone input. Geiger Bot also supports a direct line-in connection via the headset jack.

Geigerbot is a free iPhone app. For more info, or to download click here.


iGeiger is a ratemeter program. It uses the microphone to detect the clicks from your geiger counter (or other device) and display the Counts Per Minute (CPM).

The measurement period can be set between 1 and 3600 seconds, and readings can be optionally normalized to one minute (60 seconds). The displayed value is grayed out until an entire measurement period's worth of readings has been accumulated.

The minimum required volume of a click to be detected (threshold) can be set, as well as a delay time between clicks.


iGeiger is an iPhone app. For more info, or to download click here.
