Libby in the 1940s and 1950s, the method has proved to be the best absolute method for chronometric dating of organic and some carbon-containing inorganic materials. It has become an essential research tool for both archaeologists and geologists. Even broader application horizons have been opened to radiocarbon dating by use of the accelerator mass spectrometer, which allows routine analysis of submilligram samples. Art curatorship and art conservation directly benefit from this development.There are pronounced similarities between application of radiocarbon dating in archaeology and art research but there are also major differences which make it difficult to simply take a methodology developed for archaeological research and apply it directly to radiocarbon dating of art objects.In both fields the application of dating techniques focuses on dating an object of unknown age or cross-checking the age of an object previously dated by other methods.

However, until recently, little was known about the indoor concentrations of photochemical oxidants in the museum environment or the potential risks they might pose to museum collections. For this reason we began, in the early 1980's, to measure the indoor/outdoor (I/O) concentration ratios of ozone in a selection of buildings which represented a range of ventilation, architectural and collection types. A computer model was developed which predicted indoor ozone concentrations based on a combination of building parameters, pollutant sources and loss mechanisms. In parallel, experiments were established that exposed natural and synthetic colorants, on various substrates, to ozone at concentrations found in Los Angeles photochemical air pollution.

Current research includes indoor and outdoor pollution studies of museum microenvironments and biodeterioration, and research on seismic isolation and mitigation. Future trends of the GCI's environmental research are also outlined and specified.

The change in the spectral peak pattern with increasing atom bombarding dose is examined in light of the radiation damage accumulation in the surface layer of the polymer and surface morphology development at higher atom bombarding doses. The correlation of the fragment ion yield with surface morphology shows that the overall change of the bombarding geometry plays an important role in the decrease of signal intensity with time. An irregular development of the relative ion fragment yields with increasing bombarding dose indicates that processes in the surface region are more complicated than a simple radiation damage accumulation of the polymer fragments created by a polymer chain scissoring mechanism.

The aim is to monitor, measure and document the strain experienced by different areas of a tapestry while it is hanging on display. Initial research has established that damage can be identified in the early stages of its inception, i.e., before it is visible to the naked eye. The paper also reports initial results of strain data visualisation that allows curators and conservators to examine how strain develops, thereby facilitating predictions about the changes in the form or condition of the tapestry. Strain data visualisation also allows the strain process to be recorded, thereby facilitating the effective documentation of display methods and conservation interventions. The article reports the use of point measurements (using silica optical fibre sensors) and full-field monitoring (using 3-D photogrammetry with digital image correlation (DIC)).
