Spectrometry of LET using track-etch detectors - Fragmentation studies and radiobiological effectiveness in heavier ion beams

Using track-etch detectors, an attempt to distinguish the contribution of primary particles and of fragments in heavy ion beams have been made. From LET spectra, dose characteristics, such as absorbed dose, dose equivalent, or quant...
