Concepts of Radiation Radiation * Emission of energy from an atom and the transmission of this energy through space. * Energy propagated in a material medium or space. * Energy in transit. What are the types of radiation? * Radiation is of two general types in our environment. * They are called non-ionizing and ionizing. Ionization * the energy transferred to the electrons causes them to be pulled away or removed from an atom entirely. * The result is the

ABSTRACT Mutation was induced via a physical agent‚ radiation. 4 levels of radiation—0 kr (control)‚ 10 kr‚ 30 kr‚ and 50 kr—were used in seeds to determine the radiation effects on the growth of Zea mays. Using two duplicate set-ups‚ each‚ planted with 18 seeds per radiation‚ the differences in height were observed from January 29 to March 17 in a 1 to 2-day interval (Mondays-Wednesdays-Fridays). Results show that as radiation increases‚ the potential of plants to grow decreases—0 kr seeds reached

The effect of mobile phone radiation on human health is the subject of recent interest and study‚ as a result of the enormous increase in mobile phone usage throughout the world. As of November 2011‚ there were more than 6 billion subscriptions worldwide.[1] Mobile phones use electromagnetic radiation in the microwave range. Other digital wireless systems‚ such as data communication networks‚ produce similar radiation. In 2011‚ International Agency for Research on Cancer (IARC) classified mobile

The effect of mobile phone radiation on human health is the subject of recent interest and study‚ as a result of the enormous increase in mobile phone usage throughout the world (as of June 2009‚ there were more than 4.3 billion users worldwide). Mobile phones use electromagnetic in the microwave range. Other digital wireless systems‚ such as data communication networks‚ produce similar radiation. The WHO has classified mobile phone radiation on the IARC scale into Group 2B - possibly carcinogenic

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

insufficient physical exercise. However‚ not all known causes of cancer such as ionizing radiation are covered to this extent. How big of a role does ionizing radiation play in cancer deaths? Is it even worth noticing? First‚ in order to understand why ionizing radiation leads to cancer‚ an important distinction must be made between ionizing and nonionizing radiation. “Radiation is ionizing if the energy of the radiation suffices to remove an electron from an atom to create an ion. Conversely‚ if the energy

INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy
