The nematode Caenorhabditis elegans was exposed to natural space radiation using the ESA Biorack facility aboard Spacelab on International Microgravity Laboratory 1, STS-42. For the major experimental objective dormant animals were suspended in buffer or on agar or immobilized next to CR-39 plastic nuclear track detectors to correlate fluence of HZE particles with genetic events. This configu...

Radon concentrations were measured with long-term alpha-track radon detectors along with radon scout. Radon gas emanates from the radium content of terrestrial products, like tobacco leaves. Smoking materials contain, beside tobacco, many other additives that may also contain radium traces. These additives aim at exciting smoker’s feeling via chemical reactions, which may be disrupted by alpha ...

We present measurements of fragmentation cross sections of relativistic nuclei and upper limits for the production probability of nuclear fragments with fractional charge using CR39 nuclear track detectors and an automated scanning system. The measurements of the total and partial charge changing fragmentation cross sections concern 16 GeV/nucleon oxygen ions, 14.5 GeV/nucleon silicon ions and ...

A brief survey of plastic scintillators for various radiation measurement applications is presented here. The utility of plastic scintillators for practical applications such as gamma radiation monitoring, real-time radioisotope detection and screening is evaluated in laboratory and field measurements. This study also reports results of Monte Carlo-type predictive responses of common plastic sc...

The successful application of the TRD tracking algorithms [1] lead to the idea to generalize and optimize those algorithms in a flexible way in order to make them applicable for other, similar detectors. In this contribution we present how this idea was realized and applied for the TRD layout optimization and for track finding in the MuCh detector. Since both tracking detector setups (TRD and M...
