Vejam que loucura este artigo da revista HIFI Review de Novembro de 1959: dispositivos atômicos para limpar os discos. Mas atômicos mesmo, com Polônio 84 : We now come to the class of cleaners that offer no physical contact with the surface of the disc – atomic radiation devices. Yes – atomic radiation has invaded the home – this time in one of its most interesting "peaceful" applications. We tested four radiation-type cleaners and found that they worked as advertised, although all had certain limitations. Products such as the Mercury "Dis-charger". Audiotex "Atom Stat-Elim", Robins "Atomic Jewel" and Nuclear Products "Staticmaster Record Brush", rely on the ability of atomic radiation to ionize the air around the record surface. This ionized air acts as a conductor, bleeding the static electricity away from the disc and back into the atmosphere. Dust is then easily removed from the grooves. The "Staticmaster" is something else again. This is a soft hair brush with a polonium strip mounted in the base. Polonium, atomic No. 84, is the key to this product effectiveness. Air ionizing alpha particles are emitted by polonium. This may sound dangerous, but the range of this particles is short (about 1 3/8" in the air) and a piece of cigarette paper is capable of interrupting radiation. Once static has been removed from the disc, the released dust may be gently brushed from the grooves. The complete operation is accomplished in one stroke while the record is rotating on the turntable – leaving it dust – and static free. Repeating the process before each play insures that records will have long, clean-sounding life. In short, this is the one of the most satisfactoty methods of cleaning records yet developed.
