1. Background Radiation
Simulated detection of background radiation. For example, in Hong Kong, the background radiation level is 1–2 counts per second.
2. Inverse-Square Law
Radiation intensity decreases linearly with the square of the distance from the source. Measured data demonstrates the inverse-square relationship in appropriate graphical analysis.
3. Isotope Half-Life
Radiation intensity decays exponentially over time. Data analysis yields a simulated half-life of 182.4 s.
4. Exponential Attenuation in Matter
Radiation intensity decreases exponentially with distance traveled in material. Data analysis gives a linear attenuation coefficient of μ = 8.4 cm⁻¹.
5. Stochastic Nature of Radiation
Measured data shows statistical distribution of random fluctuations in count rate.
