Development of passive and active dosimetry
Passive dosimetry is one of the areas in which Professor Bradley and collaborators have established international standing (see for instance the work of TrueInvivo Limited and Lumisyns Sdn Bhd). There is a clear need to demonstrate the useful response of dosimeters to a broad range of radiations, from the ultraviolet and low-energy x-rays to electrons, gamma, alpha, proton, neutron and heavy ion irradiations, as well as to develop high-throughput readout systems that perfectly augment the dosimetric devices that are on offer. No less desirable is the need for reusable/long lifetime systems that can be applied in highly inhospitable environments such as at elevated temperatures and in aqueous systems. These are just some of the areas which showcase thermoluminescence, radioluminescence and optically-stimulated luminescence solutions to various issues as well as provide an awareness of state-of–the-art systems that can serve such a broad range of radiation dosimetry needs, adaptable to the less well-endowed budget through to applications involving highly sophisticated beam manipulations.

 

Environmental mappings
Interest in environmental mappings revolves around the natural decay chains U-238 and Th-232, as well as K-40 (the so-called Naturally Occurring Radioactive Materials, NORM). It is important to establish baseline measurements for these in order to assist in the identification of strategically important natural resources and evaluate the potential environmental impact of non-nuclear fuel cycle industries. Over the past few years Professor Bradley and collaborators have already produced environmental radiation mappings of Kuwait and Qatar, as well as regions in Malaysia and Thailand.

 

Toxicological studies using radiation-based techniques
This research project looks into the emissions and products that can have deleterious human health effects in terms of their potentially toxic and subtoxic composition, with exposures appearing both in domestic as well as wider settings. This research project examines various building materials for domestic and industrial purposes, foodstuffs, cosmetics and transport emissions with both stable elements (e.g. heavy metals) and radiological interests in the purview.
