International Journal of Medical and Biological Sciences 6 2012 Estimation of Electromagnetic Radiation from Base Station Antenna R. K. Singh Abstract—In the present paper‚ an observation of electromagnetic radiation from base station antennas installed for various communication purposes has been done on the basis of equivalent isotropically radiated power (EIRP) calculations. For this purpose‚ a typical wireless communication site has been selected where GSM‚ CDMA‚ 3G/UMTS and WiMAX antennas are

simulations show that a combined use of textiles with the right properties as a shield provides great possibilities for reduction of the RF effects over the human body. This can be proved from the results obtained at probe 1 which estimate the amount of RF radiation below the skin layer‚ are showing that the average SAR level with all kinds of shielding materials is ≥ 400 % lower than in the case without shielding (in the case with both shielding materials the reduction is > 300 times in the strength of the

Light Absorption by Photosynthetic Pigments in Silver Beet Abstract The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a‚ chlorophyll b‚ and carotene via chromatographs. Chlorophylls were then separated and an absorption spectra created using results obtained from a spectrophotometer. It was clear there were two distinct peaks
