background: radon concentration was measured in the soil and indoor of amman and al- rusaifa cities in jordan during summer season. materials and methods: the measurement was performed using time-integrated passive radon dosimeters, containing a solid state nuclear track plastic detector, commercially known as cr-39. results: radon concentration levels in the soil ranged from 2.8 ± 1.2 to 6.9 ±...

We propose to implement one passive nuclear track detector array of 400 m at the Chacaltaya High Altitude Laboratory (5230 m a.s.l.). The main purposes of the experiment concern the searches for magnetic monopoles of relatively low masses at the Parker bound level, searches for low mass nuclearites, and searches for some supersymmetric dark matter candidates (Q-balls).

By the use of Cr-39 particle track detectors immersed in the electrolyte, we confirm that a nuclear reaction of as-yet unknown nature can take place during electrolysis. With Li2SO4 dissolved in D2O or H2O and either Pd or Ni as cathodes, a very large statistical difference in nuclear track generation is found between detector chips immersed during electrolysis and the control chips immersed in...

BACKGROUND People are exposed to ionizing radin from the radionuclides that are present in different types of natural sources, of which phosphate fertilizer is one of the most important sources. Fertilizers are commonly used in agricultural field worldwide to enhance the crop yield. MATERIALS AND METHODS In the present investigation, a control study was carried out on the lady's finger plants...

We analyze the information that one can learn about the state of a quantum two-level system, i.e. a qubit, when probed weakly by a nearby detector. We consider the general case where the qubit Hamiltonian and the qubit’s operator probed by the detector do not commute. Because the qubit’s state keeps evolving while being probed and the measurement data is mixed with a detector-related background...

Nuclear emulsion, a tracking detector with sub-micron position resolution, has played a successful role in the field of particle physics and the analysis speed has been substantially improved by the development of automated scanning systems. This paper describes a newly developed automated scanning system and its application to the analysis of nuclear fragments emitted almost isotropically in n...
