Performance of Handheld NaI(Tl) Spectrometers as Dosimeters by Laboratory and Field Dose Rate Measurements

0 Comments
Within the framework of the IAEA Coordinated Analysis Challenge (CRP) J02012 on ‘Advancing Radiation Detection Tools for Detecting Nuclear and Different Radioactive Materials Out of Regulatory Management’, the properties of two industrial devices (1) InSpector 1000 analyzer (Canberra), with a 2″ × 2″ NaI(Tl) scintillator and (2) RIIDEYE M-G3 analyzer (Thermo Scientific), with a 3″ × 3″ NaI(Tl) scintillator, have been evaluated as dosimeters by laboratory and area measurements.
Within the Ionizing Radiation Calibration Laboratory (IRCL) of the Greek Atomic Power Fee, the NaI(Tl) spectrometers have been examined in an effort to measure Ambient gamma Dose Equal Price (ADER). The NaI(Tl) scintillators have been irradiated in a homogeneous area with 662 keV photons with completely different ADER values from 0.17 to 100 μSv h-1 at 0° incidence (irradiation area perpendicular to the detector’s entrance window) and at 90° incidence.
For every irradiation, the measured ADER by the spectrometers and the ‘true’ ADER values (offered by the IRCL) have been in contrast. As well as, the angular dependence (0-359°) of the ADER response of the spectrometers was studied with a 152Eu supply positioned at 1, 2 and three m from the spectrometers. The ADER dependence as perform of the space from the 152Eu supply (at 0° incidence) measured by the 2 detectors was in contrast with the theoretical one.
Within the area research, ADER was measured by the spectrometers at seven areas belonging to the Greek Early Warning System Community (which is predicated on Reuter-Stokes ionization chambers). These areas have completely different ADER values starting from 20 to 120 nSv h-1. In these areas, gamma ADER have been additionally deduced (1) by in situ gamma spectrometry measurements with moveable Germanium HPGe detectors and (2) by the Reuter-Stokes ionization chambers (by subtraction of the cosmic radiation).
Gamma dose measurements have been additionally carried out with the InSpector 1000 and RIIDEYE M-G3 detectors in 25 areas (seashores) of Northern Greece and in contrast with the ADER values deduced by sand pattern evaluation with gamma spectroscopy. Seashores with sand are good candidates for such kind of measurements since they’re generally flat and in precept the pure radionuclides are homogenously distributed.
Design and optimization of a complicated time-of-flight neutron spectrometer for deuterium plasmas of the massive helical system
A time-of-flight neutron spectrometer based mostly on the Time-Of-Flight Enhanced Diagnostic (TOFED) idea has been designed and is beneath improvement for the Massive Helical Gadget (LHD). Will probably be the primary superior neutron spectrometer to measure the two.45 MeV D-D neutrons (DDNs) from helical/stellarator plasmas.
The primary mission of the brand new TOFED is to review the supra-thermal deuterons generated from the auxiliary heating methods in helical plasmas by measuring the time-of-flight spectra of DDN. It can additionally measure the triton burnup neutrons (TBNs) from the d+t reactions, not like the unique TOFED within the EAST tokamak. Its functionality of diagnosing the TBN ratios is evaluated on this work.
This new TOFED is predicted to be put in within the basement beneath the LHD corridor and shares the collimator with one channel of the vertical neutron digital camera to outline its line of sight. The gap from its main scintillators to the equatorial airplane of LHD plasmas is about 15.5 m. Based mostly on Monte Carlo simulation by a GEANT4 mannequin, the decision of the DDN power spectra is 6.6%.
When projected onto the neutron charges which are sometimes obtained in LHD deuterium plasmas (an order of 1015 n/s with impartial beam injection), we count on to acquire the DDN and TBN counting charges of about 2.5 · 105 counts/s and 250 counts/s, respectively. This may permit us to research the DDN time-of-flight spectra on time scales of 0.1 s and diagnose the TBN emission charges in a number of seconds with one instrument, for the primary time in helical/stellarator plasmas.
Cell-phone digital camera Raman spectrometer
On this report, we describe the design, building, and operation of a cell-phone-based Raman and emission spectral detector, which when coupled to a diffraction grating and cell-phone digital camera system supplies means for the detection, recording, and identification of chemical substances, medicine, and organic molecules, in situ via their Raman and fluorescence spectra.
The newly constructed cell-phone spectrometer system was used to report Raman spectra from varied chemical substances and organic molecules together with the resonance enhanced Raman spectra of carrots and micro organism. As well as, we current the quantitative evaluation of alcohol-water Raman spectra, carried out utilizing our cell-phone spectrometer.
The designed and constructed system was additionally used for setting up Raman photos of the samples by using a place scanning stage together with the system. This compact and moveable system is nicely fitted to in situ area purposes of Raman and fluorescence spectroscopy and may additionally be an built-in characteristic of future cell-phones.
Ultrahigh delicate transient absorption spectrometer
Transient absorption (TA) spectroscopy is taken into account as a robust method that displays the ultrafast dynamics of photogenerated carriers in photoelectric and photocatalysis supplies. Nonetheless, restricted by its sensitivity, the photogenerated provider density in TA measurements of photo voltaic power supplies is normally a lot increased than that in the actual working situation.
Right here, we current a mixture of kHz macro-pulse and MHz micro-pulse method for an ultrahigh delicate TA spectrometer, which improves the sensitivity to the 10-7 stage of ΔOD. It allows us to review ultrafast provider dynamics pumped by very low energy, which might keep away from the affect of many-body interactions and the nonlinear impact related to excessive provider density.
