“…where A is the area of the distribution, µ is its centroid and σ 2 is the variance of the Gaussian distribution. For fitting the α-spectra of 222 Rn and its short-lived progenies, a composite model of the sum of three Gaussian distributions is applied: However, certain factors could lead to an additional asymmetric broadening of the αpeaks [12]. In the current case of spectroscopy of 222 Rn absorbed in plastic scintillators, we anticipate that the major contribution to the peak asymmetry is the observed in previous studies [6,7] non-uniformity of the photocathode response of the used PMTs.…”

“…The problem of finding suitable analytical function to fit the asymmetric α-peaks has been the subject of many studies [13][14][15][16]. An overview and a historical account in the development of analytical function to fit α-spectra from plastic scintillators are given in Chapter 11 in [12]. Here, we propose an improved model for approximating alpha-spectra obtained with plastic scintillators which is based on the Exponentially Modified Gaussian (EMG) distribution.…”

This work shows a study of the effect of the non-uniformity of photocathode response on 8 the energy resolution of plastic scintillators optimized for pulse-shape discrimination. 9The studies were performed with Hamamatsu R7600U-200 and R9779 photomultiplier tubes. The pulse-height and pulse-shape spectra were obtained for a small piece of radon-222 loaded plastic scintillator positioned at different places on the photocathode. We show that alpha spectra can be approximated well with a normal distribution if the nonuniformity of the photon response of the photocathode is minimized. In the cases when the non-uniformity cannot be minimized, we propose an analytical function which describes well the shape of the alpha peaks in a broad set of conditions. A possible effect of the non-uniformity of the photocathode response on the primary activity measurements by liquid scintillation counting is highlighted.

The characterization of a scintillating metal organic framework (MOF) is not straightforward, mainly due to the small size and low density of the material. In this context, we present herein a generic method to give an easy access to the determination of a key parameter in the scintillation field, namely the light output. To reach this, MOF‐205 was first synthesized as millimetric‐size single crystals then sintered under pressure and temperature conditions to afford a pellet. The density was increased by 300% while maintaining optical properties on par with scintillation application. The as‐prepared scintillator was then characterized in terms of photoluminescence (PL; UV‐excited emission spectrum, time‐correlated single photon counting) and radioluminescence (RL) spectroscopy (beta‐excited emission spectrum, alpha, beta and gamma pulse height spectra, alpha/beta and alpha/gamma discrimination). Results were compared with commercial BC‐404 plastic scintillator performances as well as supported by MCNP6.2 simulation.
