Radioactive Sources for Classroom Use, Options Available

ATTENTION! After 18 months of shelf life, the radioactive sources are useless for experiments. Therefore we generally do not carry stocks of this item.

The Radioactive Sources are securely mounted in a 25mm diameter and 5mm thick plastic disc, clearly labelled with the radiation symbol. While their radioactivity level is very low, caution should still be exercised, and prolonged carrying or placing in pockets against the body should be avoided.

These school-grade sources do not require licensing, but careful handling is essential. Following a set of guidelines ensures safe usage:

1. Minimise unnecessary handling and refrain from placing them in pockets or carry bags.
2. Always use tongs or forceps to handle the sources, keeping them at least 300mm away from the user.
3. Handle alpha sources with extra care to prevent damage to their delicate metallic coating.
4. For alpha sources, a thin aluminium sheet provides sufficient absorption, while beta sources require about 4 to 6mm thick lead, and gamma sources require 25mm thick lead to absorb 80% of the radiation.

Adhering to the above precautions allows for responsible and secure exploration of radioactivity in educational settings.
