There are two ways in which radioactive materials can affect the surrounding environment; irradiation and contamination. Understanding the differences between these two effects is important in terms of the precautions that must be taken when handling radioactive sources and also when storing radioactive waste. Irradiation refers to the transfer of energy (via ionising radiation) without … Continue reading Irradiation and Contamination
Surface Colour and Cooling
In the same way that surface colour affects the rate at which objects heat-up and the maximum temperature that they reach (as discussed here) so too will the surface colour affect the rate of cooling. As before, there is a standard experiment that you are expected to know and a typical set of curves that … Continue reading Surface Colour and Cooling
