Photoelectron counting distributions are obtained for radiation, consisting of a coherent and a chaotic component, after passage through the turbulent atmosphere. Independent additive background radiation is also taken into account. The counting distributions broaden markedly, and their peak occurs at decreasing count numbers for increasing turbulence. Plots of the distributions are presented f...

Radon exposure to the public contributes more than half of all the radiation doses caused by natural radiation; accurate measurement of radon progeny is quite essential for the dose evaluation of radon exposure in environment. For the purpose of establishing a radon progeny standard and controlling measurement quality of commercial devices, it is quite important to analyze the efficiency of dif...

Resonant interactions between energetic electrons and whistler mode waves are an essential ingredient in the space environment, and in particular in controlling the dynamic variability of Earth's natural radiation belts, which is a topic of extreme interest at the moment. Although the theory describing resonant wave-particle interaction has been present for several decades, it has not been hith...
