Some studies suggest that there is no evidence that cellphone can cause cancer‚ others are saying that there are credible amount of evidence that the use of cell phone cause health complication including cancer. According to the article “Dangers of today technology” Recent research shows that cellular phones can cause health complication‚ including cancer. “Heavy long exposure to cell phone radiation increases risks for certain type of cancer

Is Cell Phone Radiation Really Harmful? With sixty percent of the world’s population using cell phones‚ recent concern has risen from the medical front concerning the harmful effects of cell phone use. All scientific research has concluded that mobile phones do produce RF energy and emit electromagnetic radiation. Studies have also concluded that high levels of RF energy can be harmful to human health. However‚ all scientific studies have not agreed if the levels of RF energy emitted from modern

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

radioactivity is the treatment of cancer. Yes‚ radiation therapy is utilized for treatment of many types of cancers. Radiotherapy: a method to destroy cancer cells by irradiation with radioactive isotopes or X-rays. a. Explain briefly how radioactivity can cure some types of cancer. beta particles can cure skin cancer but not inside the body The main scooby dooby on this is that the biological damage done to some kinds of cells by exposure to radiation is greater than others. And we frequently see

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

It’s all around us. Radiation is categorized into two groups: ionizing‚ and non-ionizing. Ionizing radiation consists of particles‚ gamma rays‚ or X-rays with sufficient energy to create ionization in the medium it passes through. It has enough energy so that while an interaction with an atom takes place it can withdraw tightly bound electrons from an atom‚ thus making the atom charged or ionized. It includes alpha particles‚ beta particles‚ and gamma rays. Ionizing radiation has made a large impact

ionising and non-ionising radiation there are many side effects‚ risks and limitations. In ionising radiation‚ there is a risk of cell mutation which can result in developing cancer if there is overexposure of the radiation to the patient’s. In the worst state this radiation can result in death. This type of radiation is not recommended to the groups of people like children‚ pregnant women or the elderly as it will expose them to higher radiation than non-ionising radiation. On the other hand‚ non-ionising

Cosmic Microwave Background Radiation The Big Bang theory predicts that the early universe was a very hot place and that as it expands‚ the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang‚ called the “cosmic microwave background radiation”‚ or CMB. The CMB is an almost-uniform background of radio waves that fill the universe. The CMB is‚ in effect‚ the leftover heat of the Big Bang itself - it was released when

The Cosmic Microwave Background Radiation Perhaps the most conclusive (and certainly among the most carefully examined) piece of evidence for the Big Bang is the existence of an isotropic radiation bath that permeates the entire Universe known as the "cosmic microwave background" (CMB). The word "isotropic" means the same in all directions; the degree of anisotropy of the CMB is about one part in a thousand. In 1965‚ two young radio astronomers‚ Arno Penzias and Robert Wilson‚ almost accidentally

ASBESTOS POISONING I. ABSTRACT Asbestos poisoning also called as asbestosis is an interstitial pulmonary fibrosis that is caused by asbestos exposure. When asbestos containing materials break down or disturbed‚ its microscopic fibers become airborne that can easily be inhaled or swallowed and can cause serious health concerns in the long run. II. THESIS STATEMENT Asbestos poisoning is the impact that asbestos exposure can have on humans. Its toxicity stems from the fact that the microscopic
