Instructions to Authors

1. Purpose
RADIOISOTOPES has been published by the Japan Radioisotope Association (JRIA), a public interest incorporated
foundation, since 1952. The journal aims to serve as aforum for presenting manuscripts and material information
covering a wide range of research areas related to radioisotopes, stable isotopes, and radiation, thereby contributing to
the development of these academic areas.
2. Publication
RADIOISOTOPES is an online, open access, peer-reviewed
journal. The journal can be accessed via its oﬃcial website(members only) or the free database of the Japan Scienceand Technology Agency (J-STAGE). After being published
online, articles selected by the journal also appear in print
issues. The journal publishes three purchasable print issues
each year.
3. Editorial Policy
Manuscripts submitted to this journal are single-blind peerreviewed after being assessed for ethical compliance (seeEthical Guidelines). Reviewers evaluate manuscripts forutility, originality, and reliability and provide an honest,
fair, and logical critique based on the manuscriptsʼ merits. The Editorial Board ensures that the credibility of thejournal is maintained through a fair and prompt review ofsubmitted manuscripts and protects authorsʼ privacy anddignity without infringing any of their rights.
4. Submission Fee
To create a forum for a wide range of research on isotopes
and radiation, we allow manuscript submissions from both
members and non-members without levying any submission fee or page charges.
5. Manuscript Types
Articles: These are original manuscripts with deﬁnite conclusions.
Reviews: These are comprehensive summaries of recent innovations that fall within the scope of the journal. Reviews
should focus on concepts and critical evaluations rather
than broadly summarizing the research conducted in a ﬁeld.
Notes: These are short original manuscripts focusing on
methodology, experimental procedures, techniques, improvements in apparatus, novel attempts, or applications.
Technical reports: These are short articles that focus onpractical merits such as new applications, or the validationof known apparatus, products, or reagents.

Preliminary reports: These are articles that report original
and important ﬁndings or conclusions. Preliminary reports
are accepted when the Editorial Board prioritizes them overother papers. Authors can submit the full manuscript as anarticle later.
Materials (Data): These are reports on materials, commentaries, and surveys on research work and technical problems.
Special Issues: These are published as a series of manuscripts on a speciﬁc research ﬁeld that summarize the present status and future perspectives of the ﬁeld.
Lectures: These are lucid articles focusing on a specificresearch ﬁeld.
Commentaries: These describe a speciﬁc ﬁeld of research.
Mini reviews: These provide a short overview of recent
trends in a speciﬁc research ﬁeld based on an analysis of afew manuscripts.
Comments (Letters to the Editor): These cover articles
published in the journal in the span of one year. When they
focus on a speciﬁc article, the Editorial Board, as a generalrule, invites the authors of that article to respond.
6. Ethical Guidelines
1) Fraudulent acts such as fabrication, falsiﬁcation, plagiarism, double submission, double publication, andcopyright infringement, whether intentional or negligent, are unacceptable.
(1) Fabrication is the production of data and/or research
results that do not exist.
(2) Falsification is the intentional misrepresentation or
inauthenticity in the representation of research materials, equipment, or processes to change research data or
results.
(3) Plagiarism is the use of ideas, analysis, data, results,
manuscripts, or terms of other researchers without theirconsent or proper indication.
(4) Double Submission occurs when manuscripts withthe same or similar research content (including thosesubmitted and accepted) are submitted to two or morejournals; or substitutions are made in other languages; orthe “salami method” is used, that is, the results of a single
research project are segmented and submitted acrossmultiple papers.
2) To create a forum for a wide range of research on isotopes and radiation, we allow manuscript submissions
from both members and non-members without levying
any submission fee or page charges.
3) Conference presentations are considered as progressTable 1

or Sv instead of Ci, rad, or rem, respectively).
7) The nomenclature of compounds should follow either
the IUPAC nomenclature, the Chemical Abstracts index, or the Ring Index nomenclature. Authors must be
consistent in their nomenclature usage throughout themanuscript.
8) The mass number of nuclear species should be expressed on the upper left of the element symbol, suchas 60Co, 131I.

They must carefully determine the width of the lines,
font sizes, and complexity of the ﬁgures.
2) Figures need to be presented after tables and numberedusing Arabic numerals in the order in which they appear in the text. Titles and descriptions (ﬁgure legends)
should be placed below each figure. Authors should
indicate the positions of ﬁgures and tables in the maintext.
3) The descriptions of ﬁgures and tables should be written in English (except for “Materials,” which should
be in Japanese) even when the manuscript is written in
Japanese.
4) When figures and tables are cited in the text, theyshould be written as “Fig. XX.” “Figure XX” must be
written at the beginning of the sentence. Tables should
