[en] It is the purpose of this paper to describe some possible uses of solid state nuclear track detectors in certain experiments which could be carried out at the senior levels of a school science course or in undergraduate physics courses. A description is also given of some experiments which might profitably be carried out in senior undergraduate physics laboratory classes or in postgraduate courses devoted to various aspects of applied nuclear science.

[en] During the last 20 years, research in the field of solid state nuclear track detectors (SSNTDs) has provided material scientists and technologists with new techniques for the characterization and micromachining of materials. A number of radiographic techniques suitable for the characterization and quality control of the materials have been developed. These are briefly summarized. (author)

[en] The reliability of outdoor radon concentration measurements using the track-etch technique is affected by the environmental conditions. Studies have been made to improve stability of nuclear tracks in detector material and to achieve a stable dosemeter response. A dosemeter was developed utilizing chemically etched MA-ND/α (CR-39) detector which is thermally insulated and protected against solar irradiation. The calibration showed that its response amounts to 0.21 ± 0.03 tracks m^-2/Bqm^-3 day and was found to be in good agreement with theoretical prediction. (author)

[en] In order to develop new polymeric track detectors of high sensitivity, we have introduced sulphonate groups to thermosetting resins with a three-dimensional network structure. The test sample of the co-polymer of CR-39 with diethylene glycol bis(allyl sulphonate), DEAS, shows about three times higher sensitivity than that of CR-39 for 6 MeV alpha particles and 1.7 GeV n^-1 iron nuclei. The sensitivity for protons, however, has not yet been increased. The further improvement of this sample, SR-86, will open new fields of application for track detectors. (author)

[en] Papers are briefly summed up presented at the 10th International Conference on Solid State Nuclear Track Detectors held from July 2nd to 7th, 1979 in Lyon, France. The proceedings were divided into three main sessions, ie., Fundamental Mechanisms, Detector Methodology, Applications, and into 19 specialized sessions. (J.B.)

[en] Neutron Radiography (NR) is a well-established, non-destructive technique. For neutron imaging, various types of solid state nuclear track detectors (SSNTDs), in combination with suitable neutron converter screens, are used. The properties of SSNTDs which make them suitable for this purpose are summarized. (author)

[en] Several techniques have been developed to measure radon indoors.The use of a Solid State Nuclear Track Detector closed in a cup, has turned out to be the most appropriate for long term measurements. The Medical Physics Department of the Athens University is carrying out radon measurements in dwellings, apartments, outdoor air and mines since 1996. For this purpose a simple device, the so called Medical Physics Department radon dosimeter, has been constructed, which measures the radon concentration averaged over a long period of time. In the present paper the calibration technique introduced and the results of the calibration of the Medical Physics Department. (authors)

[en] Radon anomalies prior to an earthquake have been considered as an important precursor for earthquake prediction. The study of radon anomalies for earthquake prediction, however, require long term continuous monitoring. The solid state nuclear track detectors are well suite for such study. The radon concentration variations, prior to an earthquake, have been observed at four different stations by us with variable detector exposure time and holes, having different depths augured for radon monitoring. A positive correlation has been observed between radon build up and occurrence of an earthquake at many instances even when the distances between the radon monitoring stations and earthquake epicenters was as far as hundreds of kilometers. It has further been observed that radon signal for the arrival of an earthquake is received earlier and more enhanced in deeper holes in which radon monitoring device (steel tube containing CN-85 plastic track detector) is placed.
