Abstract.The radioactive contamination of a BaF2 scintillation crystal with mass of 1.714 kg was measured over 101 hours in the low-background DAMA/R&D set-up deep underground (3600 m w.e.) at the Gran Sasso National Laboratories of INFN (LNGS, Italy). The half-life of 212Po (present in the crystal scintillator due to contamination by radium) was measured as $ T_{1/2}({}^{212}Po)$ = 298.8±0.8(stat.)±1.4(syst.) ns by the analysis of the events' pulse profiles. The 222Rn nuclide is known as 100…

Into darkness: From high density quenching to near-infrared scintillators
In many aspects measurement of the α/β ratio has advantages over other methods. It provides higher precision and higher density of excitation than is available with Compton or photoelectric effect
Low background scintillators to investigate rare processes
TLDR
Several cases will be outlined offering—to some extent—a discussion of several inorganic crystal scintillators' performances and their potentiality for the future.
Beta decays in investigations and searches for rare effects
Current status of experimental investigations of rare single β decays (48Ca, 50V, 96Zr, 113Cd, 113mCd, 115In, 123Te, 180mTa, 222Rn) is reviewed. Nuclei which decay through single β decay very often

Lifetime measurements of 214Po and 212Po with the CTF liquid scintillator detector at LNGS
We have studied the α-decays of 214Po into 210Pb and of 212Po into 208Pb tagged by the coincidence with the preceding β-decays from 214Bi and 212Bi, respectively. The 222Rn, 232Th, and 220Rn sources
On the possibility to search for 2β decay of initially unstable (α/β radioactive) nuclei
An alternative method to search for 2β decay is discussed. Contrary to the "conventional" approach (where only β stable 2β candidates are used), it is intended to study α/β unstable nuclei, whose 2β
Light output of Double Chooz scintillators for low energy electrons
