Nuclear Radiation Shielding Glasses and Glass-Ceramics

Dear Colleagues,

The salient features of glasses, such as low cost, large-scale production utilizing simple synthesis processes, optical transparency, moderate to high density, and good structural and thermal stability (including adequate mechanical strength), have, in recent years, been attracting much attention for their use as possible alternatives to various conventionally used types of concrete and lead-based compounds/glasses for radiation shielding purposes at nuclear energy and nuclear medicine facilities. To protect radiation workers, medical personnel, and patients at these facilities from undesired or unwanted exposure to harmful direct and indirect ionizing radiations, the shielding properties of numerous glass systems have been explored, recently, through experimental techniques or appropriate theoretical approaches and Monte Carlo simulations. Specifically, the gamma and fast and thermal neutron radiation shielding characteristics of glasses (borate, tellurite, phosphate, etc.) with heavy metal oxides (BaO and/or Bi₂O₃) have been substantially studied as potential nuclear radiation shields. For gamma radiation shielding, high-density glasses require heavy metal oxides in them. However, when choosing cheaper raw materials for cost-effectiveness, the performance of suitable glasses as radiation attenuators requires further investigation for their realistic application. This Special Issue will cover in detail all the relevant radiation shielding glasses and glass-ceramics evaluated by relevant experimental or theoretical and simulation methods. Short communications, full-length research articles, and review articles covering radiation shielding topics are welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Ceramics is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
