Anything in excess is always a concern for individuals as well as for our environment, and radiation is no exception. Therefore, its measurement as well reliable estimates are crucial for its control. In consequence, they ensure an improvement in our safety preparations and protection philosophies. Various disciplines of radiation dosimetry such as environmental monitoring which includes measurement of background radiation in different locations, neutron dosimetry in high energy accelerators require the application of different types of solid state dosimeters (SSDs) and different dosimetric techniques. With the objective of addressing these issues, the present issue includes nine contributory papers out of which seven deal with different methods and case studies of dose measurement/assessment.

SSDs with desired characteristics are selected to suit the requirements in different fields for dose measurement. For estimation of dose using SSDs, calibration facilities using gamma, beta and neutron sources are needed. Precise dose measurements is of course vital but so is the timely access to this information and in this regard there is an interesting contribution by A. Sankaran which reviews the influence of Ultra books connected with ipods, i-Pad like tablet PCs, smart phones together with the cloud computing on image archiving and communication systems useful for medical diagnostics tools like CT, PET and MRI. In another review article, N. Praveena and coauthors deal with the emergency scenario which requires the in vitro monitoring of radiation workers handling actinides and demands a recovery of radionuclide like Pu, Am and U which is fast and efficient. Here, they report how the usage of extraction chromatography instead of the present practice of ion exchange drastically reduces the separation time from three days to three hours. The concern regarding measurement of distribution of naturally occurring radionuclides in ground water has been addressed by Nagaiah and colleagues in an elaborate manner.

For ensuring accuracy and reliability of any dosimetric service, quality control of dosimeters while in production and its field performance is critical. Further, it is equally important to ensure quality assurance (QA) of all the components in the radiotherapy treatment chain including precision in delivery of doses. In this context this issue includes a paper from A. K. Bakshi and the colleagues that detail the indigenous development of a computer controlled gamma irradiation system containing 60 Co, 137 Cs and 241 Am sources. Optically Stimulated luminescence (OSL) is the new catchphrase in dosimetric community due to its attractive features like repeated, remote and real time dose readouts and in this issue Menon et al. describe environmental dosimetry using LiMgPO 4 :Tb,B OSL phosphor. The radiation ambience of INDUS synchrotron utility comprises Bremsstrahlung radiation and photo neutrons. The interference from the former poses special problems and Dimple Verma and co-workers in their paper report application of CR-39 SSNTD and bubble detectors for dose assessment. The issue also includes an informative article on dosimetry of personnel working in Antarctica region which is peculiar due to its higher radiation levels arising from geomagnetic effect on cosmic radiation. Issues dealing with antioxidants and antibacterial properties of carotenoids isolated from micrococcus, non-dosimetric QA of treatment planning system used in radiotherapy too have been addressed in other papers.

In sum, this issue will be quite helpful in developing an acquaintance with the recent developments in these various spheres of radiation protection as well as in identifying their prospective research trends. I compliment all the authors for contributing their valuable research work for the RPE journal. I am sure that the articles published in this issue will provide quality information to researchers working in radiation dosimetry and overlapping areas.
