Abstract ”Radiation Dosimetry By Solid State Nuclear Track Detectors (SSNTDs)”. The aim of this thesis is to get new applications to the and of scintillator etch-pit for thermal method fast neutron dosimetry. The methods of sample-preparation and readout are given in a modified way. Moreover, alpha-particle spectrometry with CR-39 detector using combined chemical and electrochemical etching is studied. An alternative method doses by using the triple- a considered, effeciency reaction. for measuring high energy neutrons reaction on the carbon content is proved that this method has an CN of on having high triple-a it has been than greater that This thesis consists of eight chapters: The first chapter consists of an introduction includes different types of neutron dosimetry and ends with which the aim of this thesis. The second chapter explains Solid State Nuclear Track Detectors (SSNTDS), and the neutron interaction in the characteristics of CR-39 detector. The third chapter is about the irradiation facilities and instruments which were used during the study of this work. |
