Radioactive decay happens when an unstable nucleus changes into the nucleus of a more stable (different) element. We know that elements are defined by the number of protons in their nucleus so the only way for an atom to change into something else is by either increasing or decreasing the number of protons that it … Continue reading Alpha and Beta Nuclear Decay
Irradiation and Contamination
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
