The total whole-body exposure dose in indoor wireless networks is minimized. For the first time, indoor wireless networks are designed and simulated for a minimal exposure dose, where both uplink and downlink are considered. The impact of the minimization is numerically assessed for four scenarios: two WiFi configurations with different throughputs, a Universal Mobile Telecommunications System ...

BACKGROUND Recent analysis has demonstrated a remarkably consistent, nonlinear relationship between estimated inhaled dose of combustion particles measured as PM(2.5) (particulate matter with aerodynamic diameter ≤ 2.5 µm) and cardiovascular disease mortality over several orders of magnitude of dose--from cigarette smoking, environmental tobacco smoke (ETS) exposure, and ambient air pollution e...

Rural areas of developing countries have various indoor air pollution sources along with solid fuels used for cooking. This study aims to compare five sources, viz., incense stick, dhoop, mosquito coil, cigarette, and cooking fuel charcoal, respect their potential. The monitoring PM, CO, CO2, NO2, particulate bound heavy metals was carried out. Dhoop (DH1) found be emitting the highest concentr...

We measured radon (222Rn) concentrations in Iowa and Minnesota and found that unusually high annual average radon concentrations occur outdoors in portions of central North America. In some areas, outdoor concentrations exceed the national average indoor radon concentration. The general spatial patterns of outdoor radon and indoor radon are similar to the spatial distribution of radon progeny i...

In this study 222Rn (Radon) measurement were performed in water and soil gas and also both 222Rn and 220Rn concentrations were determined in air of Mansa and Muktsar district of Punjab, India. The data then used for calculation of the annual effective dose for health risk assessment of public. Totally 35 locations have been selected for the measurements. All measurements (222Rn and 220Rn) were ...

indoor radon concentrations, the annual effective dose rate and the annual equivalent dose rate to the lung and to the public were measured in the dwellings of 10 neighborhoods located on the west side of the river tigris (al-karkh) in baghdad city using passive dosimeters. cr-39 solid state nuclear track detector (ssntd) technique was used for radon measurements. ninety-one dosimeters were dis...
