The SEM-5704 simulated-radiation apparatus lets students observe results resembling nuclear-radiation phenomena without real nuclear sources or cumbersome radioactive-isotope handling, making it an ideal teaching aid. It simulates count-rate recording and background detection, inverse-square radiation intensity, isotope half-life decay, exponential attenuation through materials, random emissions and statistical distributions, and identification of unknown radiation-particle types. A large transparent window permits observation, source-detector distance is detected automatically, and data are recorded manually or automatically on an SD card.

Understand background radiation; study the inverse-square relationship between radiation intensity and detection distance; study isotope half-life and source-intensity decay over time; attenuation through matter; radiation randomness; distinguish α, β, and γ radiation. 1. Background radiation: Simulate detection; in Hong Kong, for example, background is 1-2 counts per second. 2. Inverse-square law: Radiation intensity decreases linearly with the square of source-detector distance, as stated in the source. Appropriate plots of measured data demonstrate inverse-square behavior. 3. Isotope half-life: Intensity decays exponentially with time. Plot analysis gives a half-life of 182.4 s. 4. Exponential absorption in matter: Intensity decays exponentially with travel distance; plotted data give linear absorption coefficient m=8.4 cm-1. 5. Randomness: Plots show the statistical distribution of random count-rate fluctuations.
Perform traditional nuclear-radiation experiments without real radioactive sources and obtain results for all radiation phenomena. Avoid nuclear-radiation injury, psychological concerns, source-use safety responsibilities, and administrative or technical source-handling procedures. Suitable for nuclear-physics teaching from primary through university levels and simulated training in nuclear technology or radiation medicine to reduce trainees' exposure. An audible simulated detector imitates a Geiger-Müller counter. Adjustable simulated background reflects local conditions. Simulated-source radiation characteristics can be customized. A large transparent front door aids observation. Android devices remotely control experiments. Data acquisition is manual, by SD card, or wirelessly through Android.
