Is it possible to predict which cubes or coins will land on a certain side? 6.4.2.4 How to handle radioactive sources safely to avoid contamination. Radioactive contamination is the unwanted presence of materials containing radioactive atoms on other materials. The hazard from contamination is due to the decay of the contaminating atoms. The type of radiation emitted affects the level of hazard. 0.7 Describe how radioactive contamination can occur. If radiation is dangerous, why is it used in schools? How would a person become contaminated by radiation? Explain how the procedure followed by people dealing with radioactive sources reduces the risk of contamination. If a person gets contaminated by radiation how are they decontaminated? Compare precautions taken by a teacher handling radioactive sources with those used by, say, in a nuclear power station.
