Description	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 the bottom 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.

(en) 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 tvaru o objemu 0,5 l a detektoru Kodak LR 115, který je umístěn na dně difisní komůrky. Velikost byla zvolena kvůli možnému vlivu depozice přeměnových produktů radonu. Kodak má spektrometrické vlastnosti - stopy jsou vizualizovány jen pro alfa částice o energii mezi 1MeV a 3 MeV (cs)
