The anomalous excess of low-energy νe events measured in the MiniBooNE experiment is explained through a renormalization of the absolute neutrino flux and a simultaneous disappearance of the νe’s in the beam, which is compatible with that indicated by the results of Gallium radioactive source experiments. We present the results of the fit of MiniBooNE data (Pνe→νe = 0.64 +0.08 −0.07) and the co...

The Geological Survey of Sweden (SGU) has been conducting airborne gamma spectrometry measurements of natural radioactivity in Sweden for more than 40 years. Today, the database covers about 80% of the country's land surface. This article explores the first step of putting this data into use in radioactive source search at ground level. However, in order to be able to use the airborne backgroun...

The fission fragments and heavy ions tracks in CR-39 detectors registered by Cf-252 radioactive source have been observed by using photo-spectrometric techniques. CR39 detectors were exposed at 5 cm distance from radioactive source for registering nuclear tracks created by nuclear particles emitted from Cf-252 radioactive source. Cr-39 detectors were etched in 6N NaOH solution at 70 C for 400 m...

Since the superconducting heavy ion linac ATLAS is an ideal post-accelerator for radioactive beams, plans are being developed for expansion of the facility with the addition of a driver accelerator, a production targethon source combination, and a low q/m pre-accelerator for-radioactive ions. A working group including staff from the ANL Physics Division and current ATLAS users are preparing a r...

2014 The molecule H2CN+-N2 has been observed in a mixture of N2-CH4 irradiated by alpha particles from a radioactive source. The equilibrium constant has been measured and the enthalpy of the reaction has been calculated (| 0394H0| = 7.65 ± 0.09 kcal . mole1). J.

In this paper, we present preliminary results on the feasibility of employing a low energy (2 kJ, 31 kV) plasma focus device as a portable source of pulsed neutron beams (2.45 MeV) generated by nuclear fusion reactions D-D, for the "in situ" analysis of substances by nuclear activation. This source has the relevant advantage of being pulsed at requirement, transportable, not permanently radioac...

In the present work, the general purpose radiation transport MCNPX code (version 2.5.0) was used to evaluate the neutron fluence response matrix of the passive Bonner sphere spectrometer recently developed in our laboratory. The calculations were performed for an extended neutron incidence energy range (from 10−9 MeV to 1 GeV). Afterward, a sensitivity analysis of the main parameters affecting ...

Since radiation risk is usually considered to be related to nuclear energy or atomic bomb, majority of researches on radiation protection has focused on artificial radionuclides and radioactive waste. Far less attention has been paid to radiation risk caused by exposure to ionizing radiation originating from naturally occurring radioactive materials despite the fact that their presence touches ...
