Product Details
Spark detector
Spark detector for visualising alpha particles.
Description
• The alpha radiation can be both seen and heard
• Clear demonstration of the alpha particles’ ionisation of the air
• Registers alpha radiation from radioactive minerals
• Facilitates new, exciting experiments in the laboratory
When alpha particles ionise the air in the spark detector’s aperture, sparks can be both seen and heard.
The transparent lid allows observation from several different directions.
The detector connects to a safe high voltage supply like the Frederiksen FR-366060. Normal operating voltage lies between 2 and 5 kV. The unit can be placed directly on the table. The included threaded steel rod allows mounting in normal stand material. Requires high voltage power supply available separately. Alpha radiation sources also recommended.
