XV. The magnetic and electric deviation of the easily absorbed rays from radium

Fifty years since the nuclear accident in Palomares (Almeria). Medical repercussions

In January 1966, 2 US military aircraft collided over the skies of Palomares (Almeria). One of them carried thermonuclear bombs, which released plutonium and other radioactive materials upon striking the ground. The most contaminated earth and plants were immediately removed. The Indalo Project was launched to study the effects of nuclear material on the inhabitants and environment of Palomares. A total of 1,077 inhabitants have been monitored since then, and the official version is that the ionising radiation has not been related to any type of disease. However, secrecy has surrounded much of the investigations, and no trustworthy epidemiological study has been conducted in the area. Approximately 500g of plutonium and americium remains in Palomares. Although the risk for the population appears to be low, this radioactive material should be removed as soon as possible.

Cavendish's crocodile and dark horse: the lives of Rutherford and Aston in parallel

Ernest Rutherford and Francis Aston were born a world apart but both would become two of the most influential physicists of their time. Their separate training, under the direction of J.J. Thomson at the Cavendish Laboratory, shaped their future and allowed both men to develop and apply their considerable skills in experimental physics. It also catalyzed their careers and ultimately led to each receiving a Nobel Prize. Although they had very different characters, Rutherford and Aston became close colleagues and confidants who spent considerable time together within the confines of the Cavendish Laboratory, at Trinity College, and elsewhere in Cambridge. They also traveled the world in company, usually as part of a group or British delegation of scientists attending conferences and meetings overseas. This article parallels the lives of the two men. It describes how they came to work at the Cavendish, their scientific accomplishments and accolades, and their activities and interactions away from the laboratory.
