Effective Dose Assessment for Workers in Caves in the Czech Republic: Experiments with Passive Radon Detectors
Original language description
The new RAMARN system for radon volume activity measurement was developed in 2003 and has been in use since then. RAMARN consists of a plastic chamber that is conical cylindrical in shape and about 0,5 l in volume; a bare Kodak LR 115 is located on the bottom of this diffusion chamber. The size was chosen to avoid the influence of deposited RnDP. Kodak has a spectrometric character - the tracks are visualized only for alphas with energies between 1 MeV and 3 MeV that touch the foil; thus the effective volume has a lens shape. The response therefore corresponds to diffused radon and half of 218Po born by radon gas decay. The experiments described below were conducted as one part of a routine methodology control, focused on classifying worker irradiationfrom natural ionizing radiation sources in show caves and in caves used for speleotherapy.
