Passive-Type Radon Monitor Constructed Using a Small Container for Personal Dosimetry

Eyeglass lenses for personal radon dosimetry.

Eyeglass lenses are commonly composed of allyl-diglycol carbonate (CR-39), an alpha-particle detecting plastic, thus making such lenses personal radon dosimeters. Samples of such lenses have been etched to reveal that radon and radon progeny alpha tracks can be seen in abundance, and sensitivities have been calibrated in radon chambers as a primary calibration and with a uranium-based source of...

Integrating Radon Progeny Monitor

INTRODUCTION The Japan Nuclear Cycle Development Institute (JNC) carried out research and development projects related to uranium exploration in Japan from 1967 to 1987. Several mining facilities have been retained after the end of projects. Hence, the study on the behavior and the environmental impact of radon and its progeny from the mining facilities is being continued at the Ningyo-toge Env...

a cauchy-schwarz type inequality for fuzzy integrals

نامساوی کوشی-شوارتز در حالت کلاسیک در فضای اندازه فازی برقرار نمی باشد اما با اعمال شرط هایی در مسئله مانند یکنوا بودن توابع و قرار گرفتن در بازه صفر ویک می توان دو نوع نامساوی کوشی-شوارتز را در فضای اندازه فازی اثبات نمود.

Passive neutron area monitor with CR39

Background: In high-intensity, mixed and pulsed neutron fields the use of spectrometers or area monitors with active detectors is useless in these conditions neutron measuring devices must have a passive detector. Here a passive neutron area monitor with CR39 track detector was designed and the response was calculated. Materials and Methods: The response of a passive neutron area monitor with C...
