Radon contributes with more than 50% to the dose equivalent to the public coming from natural sources, and is a major risk factor for lung cancer occurrence (10–14%, in Europe, p.a.) which should be investigated. Insufficient data on radon levels exist for Romania up to now and further extensive surveys are needed. The paper presents a series of in-situ indoor radon data in various locations in...

Particle intensity, dose equivalent and absorbed dose have been measured on board the space shuttles during their visit to the International Space Station (ISS) on STS-108 and STS-112. The dose estimates are based on very accurate measurements of recoils produced in CR-39 by cosmic ray primary and secondary protons and heavier nuclei and by secondary neutrons. The corresponding LET spectra were...

A time-efficient surface grinding and polishing procedure was developed to remove noise pitting associated with the etching of CR-39. CR-39 is a solid-state nuclear track detector used to measure and analyze ions produced by fusion implosions on the OMEGA and OMEGA EP laser systems. Using CR-39 thickness measurements acquired during the grinding process, surface removal rates of 68 µm/min and 5...

Energetic ions and ultrashort X-rays were generated by an intense ultrashort laser interacting with a copper target. Fast ions up to 3 MeV were observed with CR-39 nuclear track detector sheets when 7 TW laser was used. Cu ∼ Cu ions with the energy from 50 keV to 220 keV were detected with a Thomson parabola detector in the case of the laser power of 2.5 TW. Time-resolved X-ray diffraction was ...

Lung toxicity of chromium fumes (Cr fumes) was examined by a single intratracheal instillation into rats of 10.6 mg and 21.3 mg Cr fumes/kg body weight and by repeated (3 times) instillations of 10.8 mg and 21.7 mg Cr fumes/kg. The pathological changes were compared with those induced by single administrations of 3.2 mg and 19.2 mg Na2CO3 solution-insoluble fraction of Cr fumes (Cr-Fr)/kg and 2...

The results of the analysis of data taken in the continuation of a previously reported search1 for highly ionizing particles at PEP are presented. These data were taken in the period from October 1981 to June 1983. Assemblies consisting of Lexan and CR-39 plastic track detectors were exposed in two runs to integrated luminosities of 30 X 1O36 cm-2 and 150 X 10% crnw2% The search was sensitive t...
