I have just finished reading an excellent book that traces various theories about beta decay in the first third of the Twentieth Century. Controversy and Consensus: Nuclear Beta Decay 1911-1934 is an editted version of the successful PhD thesis written by Carsten Jensen, who clearly had a deep passion for unravelling physics history but died … Continue reading Beta Decay and Energy Conservation
Half-life, Applications and Precautions
Radioactive decay is a random process. This means that if you were to observe a lot of unstable (radioactive) atoms, you would notice that they undergo nuclear decay at unpredictable moments. But if you extended your observations for a longer period you would spot an underlying pattern. Although it is impossible to predict when one … Continue reading Half-life, Applications and Precautions
Alpha and Beta Nuclear Decay
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
