Radiation Dosimetry Phosphors : Synthesis, Mechanisms, Properties and Analysis

Radiation Dosimetry Phosphors provides an overview of the synthesis, properties and applications of materials used for radiation dosimetry and reviews the most appropriate phosphor materials for each radiation dosimetry technique. The book describes the available phosphors used commercially for their applications in the medical field for dose measurements. Although radiation dosimetry phosphors are commercially available, continuous efforts have been made by the worldwide research community to develop new materials or improve already existing materials used in different areas with low or high levels of radiation. Moreover, researchers are still working on developing dosimetric phosphors for OSL, ML, LL and RPL dosimetry.

This book provides an overall view of the phosphors available, low cost synthesis methods, mechanisms involved, emerging trends and new challenges for the development of emerging materials for radiation dosimetry. It is suitable for those working in academia and R&D laboratories in the discipline of materials science and engineering, along with practitioners working in radiation and dosimetry.

• Provides the fundamental concepts, historical context and review of current phosphors available for radiation dosimetry
• Reviews low-cost material methods to synthesize and characterize rare earth doped inorganic phosphors for different kinds of radiation dosimetry techniques
• Discusses key barriers and potential solutions for enabling commercial realization phosphors for radiation dosimetry applications
