Radioactivity in student experiments?:
- Enables students to explore key laws of radioactivity safely through hands-on experiments
- Builds understanding of both the benefits and risks of radioactivity without bias
- Designed for safe classroom use with no hazardous exposure
No samples requiring official approval:
-
Uses everyday materials instead of regulated radioactive sources
-
Eliminates the need for licensing, storage, or special handling procedures
-
All samples are sealed in protective plastic cases to prevent direct contact
-
Equivalent dose at 0.1 m is less than 0.9 µSv/h
-
Activity remains below 2000 Bq
-
Both values are well within non-regulated safety limits
-
Covers experiments such as:
-
Radioactivity in air and tap water
-
Magnetic deflection of radiation
-
Distance and absorption laws
Highly sensitive radiation meter:
-
Core component is an end-window Geiger counter tube
-
Detects alpha, beta, and gamma radiation
-
Measures equivalent dose with high sensitivity
-
Features include:
-
Digital display
-
LED indicator display
-
Acoustic signal for detection
-
Adjustable measurement duration
-
Powered by a 9 V battery
