Abstract
Carbon powder, placed in a hermetically closed apparatus under vacuum together with radium ore, adsorbs radon gas emanating from the radium ore thus producing a radioactive carbonaceous material, the radioactivity of which is due to the presence of adsorbed radon. The radioactive carbon powder thus obtained has excellent therapeutical efficacy and is suitable for a variety of applications because of the mild radioactivity of radon. Radium ore permits substantially limitlessly repeated production of the radioactive carbon powder.
Claims1
A method for the production of radioactive carbon powder with radon gas absorbed therein and capable of radiating alpha-rays using an apparatus comprising a receptacle with a removable lid capable of being closed in an airtight fashion and with means to extract air from the receptacle, comprising:
- affixing grains of radium ore contained in a bonding agent to the inside of the lid;
- placing preheated carbon powder into the receptacle;
- spraying water on the radium grains;
- pressing the lid against the receptacle, before the powder is cooled, to make the receptacle airtight;
- and
- extracting air from the airtight receptacle.
