How to identifiy the existence of natural radiation and radiactive materials using Hakaru-kun (Mr. Gamma)
Basic information on natural radiation and its dose, and human effects due to radiation exposure

This is an experiment to learn about the properties of light by using a “rainbow kaleidoscope”.

This is an experiment using a “water level gauge” to demonstrate that radiation can be “shielded” or blocked.

This experiment uses a special kit to see how radiation gets weaker with distance and to check the shielding effects of different materials and thicknesses.

This is a video that easily explains the simple radiation detector “Hakaru-kun,” including how it works, how to use it, how to measure radiation, and the concept of measurement time.
