A calculation of the expected signal due to Primakov coherent conversion of solar axions into photons via Bragg scattering in several solid–state detectors is presented and compared with present and future experimental sensitivities. The axion window ma > ∼ 0.03 eV (not accessible at present by other techniques) could be explored in the foreseeable future with crystal detectors to constrain the...

Indoor radon and thoron have been measured in the houses ofMoradabad District, Uttar Pradesh India, by means of solid state nuclear trackdetectors. Radon, an invisible radioactive gas, occurs naturally in indooratmospheres and along with thoron is the most important contribution of humanexposure to natural sources. Radon exists in soil gas building materials and indooratmosphere to name but a f...

Recent research in the field of phosphor and scintillator materials and related detectors is reviewed. After a historical introduction the fundamental issues are explained regarding the interaction of x-ray radiation with a solid state. Crucial parameters and characteristics important for the performance of these materials in applications, including the employed measurement methods, are describ...

Multimedia communication in wireless networks is challenging due to the inherent complexity and constraints of multimedia data. To reduce the high bandwidth requirement of video streaming, videos are compressed by exploiting spatial and temporal redundancy thus yielding dependencies among frames as well as within a frame. Unnecessary transmission and maintenance of useless packets in the buffer...

This paper provides a collection of data relevant to the use of various types of semiconductor detector in nuclear spectroscopy and gives examples of the use of detectors in specific experimental applications. Basic data on absorption of various kinds of radiation in germanium and silicon are given, and these are related to the characteristics of different types of semiconductor detectors. A br...

We measured the inter-strip capacitance on a prototype DC-coupled "stripixel" detector (SPD) employing circular spirals with two methods, each of them employing a RC-chip to bias and read out the detectors. Both yielded the same value of Cint = 1.1 pF for a strip length of 1.4 mm, indicating the total inter-strip capacitance to be much larger than on ordinary silicon strip detectors (SSD).

background: separate radon and thoron measurements in soil are very important in assessment of internal exposure due to inhalation of such radioactive gases. materials and methods: in this study, a low cost, small size, passive diffusion chamber has been developed for simple measurement of radon-222 and radon-220(thoron) gases separately in soil. the diffusion chamber consists of two films and ...

In this study, the results of uranium concentrations and specific activity in 10 rice samples are described using a solid-state track detector (CR-39). Samples were collected from various local Iraqi markets with different origins (Iraq, India, America, Thailand). Our findings found that concentration all studied ranging (0.55 ± 0.28 to 1.74 0.31) ppm weighted average (1.24 0.99) ppm. Also, dem...
