Effective dose assessment for works 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 used since this year.RAMARN system consists of a plastic chamber of conical form with 0,5 l of capacity and detector Kodak LR 115 that is located on f this diffusion chamber.The sice was chosen to avoid the influence of deposited decay products of radon. Kodak has a spektrometric character - the traks are visualized only for Alpha particles with energies between 1 and 3 MeV, that touch the foil.This the effective volume has a lens shape. The responce 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.

Czech description

Nový stopový detektor RAMARN pro měření objemové aktivity radonu byl vyvinut v roce 2003 a od té doby je používán. Detektor RAMARN sestává z platikové nádoby kónického tvaruo objemu 0,5 l a detektoru Kodak LR 115, který je umístěn na dně difusní komůrky.Velikost byla zvolena kvůli možnému vlivu depozice přeměnových produktů radonu. Kodak má spektrometrické vlastnosti - stopy jsou vizualizovány jen pro alfa částice o energii 1 MeV a 3 MeV.
