Electromagnetic radiation

I n 1898, the radioactive elements Radium and Polonium were found by Marie and Pierre Curie. Thus the concept of treating cancers was born. The Curie’s work on radiation led to the possibility of cancer treatment, but also provided a better understanding of the atom. That is that an atom has a nucleus at its centre with surrounding energy shells which consist of negatively charged electrons. The electron was discovered in 1897 by J.J. Tomson, and was the first proved element of the atom. The…

The CT scanner Depends upon several steps:- 1-The x-ray tube and detector transverse (scan) the object. 2-The radiation beam passes through the object and is attenuated. The intensity of radiation beam from x- ray tube and transmitted beam both are detected by suitable detectors. 3-The transmitted beam and the references beam are both converted into electric signals. 4-These output current signals are then converted into digital form by analog –to-digital converter. 5-The digital data are…

What if you found out your cell phone could kill you? Radiation is part of our natural world; however, it is often dramatically increased by man made objects (Gould, 2017). There are many different things to know about radiation, and questions to ask including what objects give off radiation, the dangers involved in radiation, and symptoms of radiation sickness. The radiation of everyday objects and the different types of radiation effect the human body in many ways which can sometimes be…

Nuclear radiation effects ERT term 4 With the depletion of fossil fuels and their harmful carbon dioxide emission, nuclear power is an increasing energy source. World-wide around 11.5% of energy is nuclear and in countries like France it’s 76.9% of their power source. With nuclear power being a renewable and relatively clean source of energy, nuclear power plants are being built all over the world. But despite the environmentally friendly aspects of nuclear power, when nuclear waste is not…

a specific characteristic of their nucleus. Radioactive isotopes, or radioisotopes, do not contain the proper amount of neutrons. As a result of this, the nucleus of radioisotopes is unstable. The instability causes them to emit particles or electromagnetic waves from…

BREAST CANCER DETECTION BY T-SHAPED SLOTTED RECTANGULAR MICROSTRIP PATCH ANTENNA Abstract This Paper shows the great achievement in the breast cancer detection by microwave imaging ,in this paper firstly the T-Shaped Slotted RMPA is designed for ISM band Application at 2.45 GHz and resonated at particular frequency by iterations on the simulation software and very low losses is shown on particular exact frequency is 32.2dB ,after that The Breast Phantom model with cancer tissues and RMPA…

Introduction Radiation protection policy is distributed among several governmental Agencies in the United States. Each agency is tasked with controlling exposure to radiation and the safe use of radioactive materials and radiation generating devices. These agencies inform their policy with reports and recommendations from a number of organizations, including the National Council on Radiation Protection and Measurements (NCRP). The NCRP is a longstanding organization that strives to provide…

We can all agree that there is nothing worse than driving down the road in your car and either getting a hard core sunburn or just being way to hot. Like everything in the world there is a solution to that, but it seems to be illegal now a days. Over the years window tint has become more popular with the new style of people and hotter summers. The solution is tinting your vehicle 's windows. Many people have had experiences with window tint and most likely were suprised if they did not know…

Ultrafast Electron Microscopy has been demonstrated to be an effective table-top technique for imaging the temporally-evolving dynamics of matter with subparticle spatial resolution on the time scale of atomic motion. A stringent enhancement of the UEM temporal resolution is demanded for recording snapshots of the electron motion which will provide a real-time access to all microscopic motions outside the atomic core and radically change our insight into the workings of the microcosm. Here, we…
