Radioactivity in student experiments :
- This experiment set allows students to explore the laws of radioactivity safely
- Helps students understand risks and benefits of radioactivity objectively
- Enables hands-on learning without hazardous materials
No samples requiring official approval:
-
Experiments use everyday household materials instead of regulated radioactive sources
-
Eliminates need for registration, storage, and special handling
-
Samples are sealed in plastic cases to prevent direct contact
-
Equivalent dose at 0.1 m is below 0.9 µSv/h
-
Activity is below 2000 Bq
-
Both values are well within safe, non-regulated limits
-
Experiments include:
-
Radioactivity in air and tap water
-
Magnetic deflection of radiation
-
Distance and absorption laws
Highly sensitive radiation meter:
-
Uses an end-window Geiger counter tube
-
Detects alpha, beta, and gamma radiation
-
Measures equivalent dose with high sensitivity
-
Features include:
-
Digital display
-
LED indicators
-
Acoustic signal for detection
-
Adjustable measurement duration
-
Powered by a 9 V battery
