My career as a radioisotope hunter

Article Abstract:

Radioisotopes discovered by chemist Glenn Seaborg in the late 1930s are used to diagnose and treat disease. Radioisotopes are radioactive forms of a chemical element. At the University of California at Berkeley, Seaborg collaborated with nuclear physicist John Livengood to identify the radioisotopes iron 59, cobalt 60, and iodine 131. Livengood used a cyclotron to bombard specific chemical elements with tiny particles called neutrons and deuterons. Seaborg dissolved the material and separated the chemicals into the element and the radioisotope. Doctors used iron 59 to study blood formation and iron metabolism. Cobalt 60 is used to treat cancer and to sterilize medical products. Iodine 131 is used to diagnose and treat thyroid disease and has other medical applications. Seaborg played a role in the discoveries of technetium 99m, which is used in many diagnostic procedures and cesium 137, an anticancer agent.

Streaming into the future

Article Abstract:

The UK's new Labour government does not appear to appreciate that the structure of the school system should be given as much attention as standards. It is possible to argue that the only really effective way to improve the standard of UK schools is to return to strict catchment areas, thus giving a valuable boost to under-performing schools. It is important to offer a variety of educational approaches, but this could be achieved within the individual schools. A system of streaming based on technical, vocational and academic routes could prove very effective.

The rustic charm and fragile ecosystem of Rock Lake may be endangered by the introduction of electricity to the campsite of the park. Electricity in the campsite will allow vacationers to bring their electric 'conveniences' that may disrupt the wildlife.
