Aim This study aimed to examine the quality of published paramedic scoping reviews against pre-existing frameworks to assess the extent to which they fulfil the requirements of this methodological approach. Subsequently, recommendations will be presented regarding improvements for future paramedic scoping reviews. Methods A scoping review was conducted guided by the PRISMA Extension for Scoping Reviews. A literature search was performed in six electronic databases as well as the grey literature to identify previous scoping reviews that focussed on paramedic or emergency medical service personnel. Relevant data were extracted from included articles and presented in narrative and tabular formats. Results The literature search initially identified 475 articles, of which 20 remained after title/abstract and full-text screening. There was a general increase in the number of studies published over time, the majority of articles (80%) had conducted their scoping review utilising published frameworks, and 75% of first authors were paramedics. Although many areas of these reports comply with published guidelines, there was an overall lack of consistency in the specific information included, the level of detail of that information, and the location of information within the reports. Conclusion All paramedic scoping studies should be reported with the use of a published framework to enable standardisation in the reporting, thus facilitating understanding, reproducibility, and utility. The PRISMA Extension for Scoping Reviews provides a checklist and thorough explanations of each step in the reporting process and is recommended for use with all future paramedic scoping reviews.

The release of ruthenium in oxygen-rich conditions from the reactor core during a severe accident may lead to formation of significantly more volatile ruthenium oxides than produced in steam atmosphere. The effect of volatile ruthenium release in a case a reference BWR nuclear plant was studied to get rough-estimates of the effects on the spreading of airborne ruthenium inside the containment and reactor building and the fission product source term. The selected accident scenario starting during shutdown conditions with pressure vessel upper head opened was a LOCA with a break in the bottom of the RPV. The results suggest that there is a remarkable amount of airborne Ru in the containment atmosphere, unlike with the standard MELCOR Ru release model which predicts no airborne Ru at all in the selected case. The total release of ruthenium from the core can be 5000 times the release predicted by the standard model. Based on the performed plant scoping studies it seems reasonable to take the release of volatile ruthenium oxides into account when assessing source terms for plants during shutdown states.
