Chernobyl nuclear plant is one of the biggest disasters in history! It happened on April 26‚ 1986. It was a nuclear radiation disaster. About 4‚000 people died. All the survivors suffered from the radiation side affects for the rest of there lives. This also ruined the environment! The nuclear plant exploded exactly at 1:23 A.M. The explosion killed two people. Then radiation started pouring out of the reactor. There were 134 emergency workers that got involved trying to figure out how to

electromagnetic radiation (EMR). EMR is a form of energy that reveals its presence when it strikes the matter. Remote Sensing has a sensor which can detect the electromagnetic radiation coming from an object. Remote Sensing data also enables direct observation of the land surface or any other objects at repetitive intervals and therefore allow monitoring the changes occurring in it through aerial or satellite sensor. Electromagnetic Radiation: Emission of EMR (Electro-Magnetic Radiation) occurs from

Many people who have skin cancer require surgery for effective initial treatment. However‚ there are several other nonsurgical options may be considered for the treatment of squamous cell and basal cell skin cancers such as topical medications‚ radiation therapy and photodynamic therapy. According to Dr. Anna Bar an Assistant Professor of Dermatologic Surgery at Oregon Health & Science University‚ there continues to be progress in nonsurgical treatments for skin cancer that are useful for people

Section 1: What is radioactivity? Nuclear Radiation During radioactive decay‚ the unstable nuclei of these isotopes emit particles‚ or release energy‚ to become stable isotopes‚ as Figure 1 shows. After radioactive decay‚ the element changes into a different isotope of the same element or into an entirely different element. Recall that isotopes of an element are atoms that have the same number of protons but different numbers of neutrons in their nuclei. Different elements are distinguished

convection and radiation. Conduction is when heat travels through solids. Hot atoms vibrate and their energy is passed on to neighbouring atoms which vibrate and become hot. Convection is the process by which heat is transferred by warm liquids or gases. Warm air is less dense than cold air because particles have more energy so they spread further. So the hot air rises and transfers heat and the cold air replaces it Radiation: all objects give out and take in thermal radiation which is also called

Ideas about the solar system Our understanding of the solar system has changed over many centuries. Scientists such as Ptolemy‚ Copernicus and Galileo added their ideas to our changing understanding. We observe the universe using a variety of equipment‚ from telescopes to orbiters and landers. Models of the solar system The planets and the Sun orbit the Earth in Ptolemy’s model. Our understanding of the universe has changed over time. Different civilisations have created different models to

Tips on Radiation Exposure CINCINNATI‚ Oct. 2‚ 2012 /PRNewswire-USNewswire/ -- With millions of X-rays performed on children every year‚ kids are more likely to receive X-rays than any other type of imaging exam. A new education campaign seeks to equip parents with the knowledge they need to make informed decisions about their kids and X-rays. Through a series of online teaching materials aimed at parents and medical professionals‚ Image Gently’s "Back to Basics" campaign promotes radiation protection

INTRODUCTION: The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. Radiation can be said to be energy that travels and spread as it goes. The "electromagnetic spectrum" of an object has a different meaning‚ and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. We tend to witness different radiations of the electromagnetic spectrum without knowing‚ example is the visible light that we see with
