[en] The Radtech Asia'95 Radiation Curing Conference was held in November, 20-24, 1995 in Guilin, China. The subjects include chemistry, application, Measurement and Equipment, and Material modification. Out of 86 titles, some 30 papers are in INIS scope

[en] In this opening address an overview of the expanding uses of industrial radiation processing and radiosterilization is given. High energy radiations are an acceptable alternative to hazardous chemicals for the production of plastics by polymerization and for medical supplies sterilization, food processing and water and sewage treatment.

[en] During the last decade radiation cured polymers have continued to grow in importance not only by expansion within existing coatings applications but also by extension into new fields of application such as ceramics, ink-jet inks and fibres. To provide a further update on the rapidly growing science and technology of radiation curing the Third International Symposium was held. Apart from providing an update on the application, chemistry and control aspects of the radiation curing the aim of the meeting was also to provide the newcomer with a basic insight into radiation curing applications. Accordingly the proceedings contained in this special publication which follow closely the format of the meeting, has five sections covering the background/trends, applications, initiator chemistry, substrate chemistry and analytical, physical chemical and health and safety aspects. There are twenty-five papers all told, three of which are indexed separately. (Author)

[en] The author discusses ion beam characterization and treatment. Almost every process that occurs when an ion beam hits a solid has been used as a technique in materials science. Some ions bounce off; backscattering is a routine technique for near-surface analysis in many laboratories. Atoms of the sample are knocked out; sputter profiling is used as an adjunct to many surface science measurements, and analysis of the ejected atoms yields information about the composition of the sample. Ions slow down in a solid, depositing energy in the sample and causing radiation damage. This makes ion beams useful in the development of radiation-resistant materials and has to be understood in order to apply other ion beam techniques. Finally, the ion stops and becomes incorporated into the ample, which is known as implantation. As well as being a vital industrial technique in the manufacture of semiconductor devices, implantation can be used in materials science wherever it is useful to change the composition of a near-surface layer. The implanted species does not have to be soluble in the sample

[en] The consolidation and restoration of a variety of wooden agricultural and farmer's tools like rakes, pitchforks, scythes, wagon shafts, a dung-fork and a baker's peel is described. The partly quite spreading objects caused some problems during impregnation and the following curing by gamma radiation. The solution of these problems is as well discussed as the restoration of the fragmented tools. (Author)

[en] Compositions comprising an impermeable acrylate-terminated oligomer, at least one reactive diluent, and 2-hydroxycyclo-hexylphenone, diethoxyacetophenone, 1-(4-dodecylphenyl)-2-hydroxy-2-methylpropan-1-one, or 2-hydroxy-2-methyl-1-phenyl-propan-1-one as a photoinitiator, are disclosed. These compositions have utility in optical coatings
