    These are the accompanying Data Sets for the Airborne Gamma-ray Mapping Using Fixed-wing Vertical Take-off and Landing (VTOL) Uncrewed Aerial Vehicles paper by Woodbridge et al., 2023. They have been processed to varying levels to show the progression and process steps. Flights_1...2-5_10Hz_RawData represent the original unprocessed 10hz data sets in both CSV and JSON format. Flight1...2-5_1Hz_K40d and Flight1...2-5_1Hz_U238 represent the partially processed 1Hz data files. The AllFlightsCombined_2hzU238 and AllFlightsCombined_2hz_K40 represent the final processed data set that was plotted and presented. NB The value -9999 is present where total dose values were not able to be calculated. This was due to there not being one of the individual unscattered peak values present. As per the paper, the data point was only considered if all three unscattered peak doses of 609, 1120 and 1764 KeV were present for U238. This was then removed from the displayed data set by only plotting values >0 in ArcGIS Pro

    Project IPAD, a database to catalogue the analysis of Fukushima Daiichi accident fragmental release material

    For the full database, please visit: www.projectipad.org The 2011 accident at Japan’s Fukushima Daiichi Nuclear Power Plant released a considerable inventory of radioactive material into the local and global environments. While the vast majority of this contamination was in the form of gaseous and aerosol species, of which a large component was distributed out over the neighbouring Pacific Ocean (where is was subsequently deposited), a substantial portion of the radioactive release was in particulate form and was deposited across Fukushima Prefecture. To provide an underpinning understanding of the dynamics of this catastrophic accident, alongside assisting in the off-site remediation and eventual reactor decommissioning activities, the ‘International Particle Analysis Database’, or ‘IPAD’, was established to serve as an interactive repository for the continually expanding analysis dataset of the sub-mm ejecta particulate. In addition to a fully interrogatable database of analysis results for registered users (exploiting multiple search methods), the database also comprises an open-access front-end for members of the public to engage with the multi-national analysis activities by exploring a streamlined version of the data

    Data from: Insect visual sensitivity in the far-red enhances contrast against vegetation

    The wavelength sensitivities of animal photoreceptors strongly influence the visual contrast of objects in the environment, thereby constraining visually-guided behaviors. Outside of the human visual wavelength range, ultraviolet sensitivity in many species provides important and behaviorally relevant visual contrast. However, at the opposite end of the spectrum, the potential benefit of far-red sensitivity remains unclear. We investigated the potential benefit of long wavelength sensitivity by modelling the visual contrast of a wide range of jewel beetle colours against the flowers and leaves of their host plants to hypothetical insect visual systems. We find that the presence of a long wavelength sensitive (LWS) photoreceptor enhances the contrasts of pairwise comparisons between leaves, flowers and beetles. When we varied the wavelength of maximum sensitivity (λmax) for the LWS receptor in a tetrachromatic system, contrasts between beetles, flowers and leaves were all enhanced with increasing λmax from 580 nm to at least 640 nm. These results show the visual advantage of longer LWS receptors in discrimination against vegetation and highlight the potential adaptive value of long wavelength and far-red sensitivity in insects
