Abstract: The files contain the Grid Ionization Chamber (GIC) spectra and radioluminescence images of the pitchblende samples presented in the corresponding article.
Other: The project 19ENV02 RemoteALPHA has received funding from the EMPIR programme co-financed by the Participating States and from the European Union’s Horizon 2020 research and innovation programme.
Remark: description of the individual files:
- block: Spectra GIC
research object: Measuring alpha activity via the alpha spectrum obtained using the Grid Ionisation Chamber (GIC)
method: GIC measures the energy distribution (spectrum) of alpha particles. The measurement time (in seconds) is reported in line 7 of each file. The energy calibration of the spectrum is given by Cal-zero and Cal-Slope in lines 9 and 10.

- block: Scanning measurements / images
research object: Imaging of pitchblende samples using radioluminescence
method: The UV images are taken in the dark with the optical scanning system from the distance of 2 m. The color image, onto which the UV image is superimposed, is taken separately in the well-lit environment with the Intel RealSense D435 depth camera. The acquisition system consisting of a lens-based UV detector and two goniometric stages controlling the pitch and the yaw of the detector. The acquisition system consists of a 240 mm UV fused silica lens, optical filter assembly, photomultiplier tube, pulse counter, and readout computer. The filter and photomultiplier type are selected depending on the measured UV band (UV-A or UV-C) with the component choice specified in the header of each measurement file. The UV photon count rate (in 1/s) is logged with the Hamamatsu C8855 counter in millisecond intervals. Two Newport goniometric stages (M-BGM160PE - pitch, RVS80CC - yaw) are controlled with Newport SMC100 controllers. Finally, two data streams - count rate and detector orientation - are synchronized to produce the UV image where each pixel is characterized by a (pitch, yaw, count rate) vector.
