Measurement of Low and Ultra-Low Background Radioactivity

Dear Colleagues,

The aim of this Special Issue is to provide an overview of the current status of low background and ultra-low background radioactivity. Experimental search of dark matter and neutrinoless double beta decay need to limit background rate as much as possible, using radio-pure materials for detectors and radio-pure electronics for data acquisition. Data analysis need to use dedicated methods to separate signal from background in the case of very weak signals. Environmental radioactivity needs also ultralow background electronics and detector components in case of very weak activities, as those due to trace elements and some cosmogenic radioisotopes, or very weak signals as those from tritium.

The scope of this Special Issue is recent advances in the field of low background and ultra-low background radioactivity from the experimental point of view. Papers on radio-pure materials and electronics, low background and ultra-low background data acquisition and analysis, shielding procedures, low-level counting detectors and related topics are welcomed.

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. Instruments 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 1400 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.
