UltimaGoldTM AB and OptiphaseTrisafe are two liquid scintillators made by Perkin Elmer EG & G Company respectively. Both commercially promoted as scintillation detectors for α β particles. In this work, the responses to γ-rays neutrons of OptiphaseTriSafe scintillators, without with reflector, have been measured aiming use these neutron detectors. Responses were pulse shape spectra in a multichannel analyzer. Scintillators exposed gamma rays produced 137Cs, 54Mn, 22Na 60Co sources. The...
This work aims to evaluate a dosimetric system composed of green malachite supported in agarose. Previous showed that solutions irradiated at 1 40 kGy present linear behavior. is gel (2.5×10–3 M), sodium benzoate (1%),and agarose (1%) was exposed tovarious doses gamma irradiation. The systems were measured with UV-V spectrophotometer 619 nm. Experimental parameters (such as dose rate, doses, and temperature) controlled optimized for reproducible reliable results. More studies are needed...
Neutrons in the environment are produced naturally and by anthropogenic activities. In nature neutrons come from interactions between cosmic rays, their secondary particles, nuclei atmosphere ground. Also, during electric discharges storms, spontaneous fission (α, n) reactions occurring soil (Geoneutrons, Telluric or Geogenic neutrons). Along chain decay of uranium thorium several radioisotopes α-emission, some alpha-particles have energies enough to induce soil. Nevertheless amount...
