Název v původním jazyce

Effective dose assessment for works in caves in the Czech Republic: experiments with passive radon detectors

Popis výsledku v původním jazyce

The new RAMARN system for radon volume activity measurement was developed in 2003 and since this year it has been used. RAMARN system consists of a plastic chamber of conical form with 0,5 l of capacity and a detector Kodak LR 115 that is located on thebottom of this diffusion chamber. The size was chosen to avoid the influence of deposited decay products of radon. Kodak has a spektrometric charakter - the traks are visualized only for Alpha particles with energies between 1 and 3 MeV, that touch the foil. Thus the effective volume has a lens shape. The response therefore sorresponds to diffused radon and half of 218 Po born by radon gas decay. The experiments were conducted as one part of a routine methodology control, focused on classifying worker irradiation from natural ionizing radiation sources in show caves and in caves used for speleology.
