Radon gas, which undergoes radioactive decay, can cause damage to the lung tissue and cancer over time in indoor environments where it is inhaled. gas radioactivity concentrations were measured using CR-39 passive solid state nuclear track detectors (SSNTD) basement ground floor simultaneously summer winter periods 17 dwellings Çanakkale (Turkey). Accordingly, an average of 163.67 Bq.m-3 baseme...

Lung cancer is considered a disease that completely happened by smoking; therefore, it preventable perfectly. Yet, small percentage of cases there, possibly as many 5 to 15%, in which there are other reasons. The risk factors acknowledged for the groups comprise passive smoking, family history cancer, occupational expo sure certain chemicals and ionizing radiation, diet. Moreover, fifty samples...

Revised 2003 (see the various sections for authors). In this section we give various parameters for common detector components. The quoted numbers are usually based on typical devices, and should be regarded only as rough approximations for new designs. More detailed discussions of detectors and their underlying physics can be found in books by Ferbel [1], Grupen [2], Kleinknecht [3], Knoll [4]...

Photonic integrated circuits require photodetectors that operate at room temperature with sensitivity telecom wavelengths and are suitable for integration planar complementary-metal-oxide-semiconductor (CMOS) technology. Silicon hyperdoped deep-level impurities is a promising material silicon infrared detectors because of its strong room-temperature photoresponse in the short-wavelength region ...
