Introduction When light interacts with matter‚ the structures and properties of atoms and molecules are determined. This technique is spectroscopy where it absorbs‚ emits‚ or scatters electromagnetic radiation. Electromagnetic radiation has particle-like properties having photons and quantum and wave-like

Everywhere I turn‚ I see someone on a cell phone‚ either talking or texting. Every car next to me in traffic has a GPS on the dashboard‚ including my own. It seems that everyone needs some help from technology on a daily basis. It both surrounds and intrigues us. Technology can be helpful‚ fun‚ and entertaining. Much of technology is created to assist with making projects faster or daily tasks more efficient. However‚ the collaboration of technologies in our lives has a few negative effects and I

Chemotherapy is the treatment of disease by the use of chemical substances‚ especially the treatment of cancer by cytotoxic and other drugs. Chemotherapy and radiation do not always fully cure cancer in the body. It separates cells in the body which affects hair‚ nails‚ skin‚ the digestive system‚ and the blood. This procedure makes you very ill and can cause lifelong damages to various parts of the body‚ including your brain‚ liver‚ hearing‚ and reproductive organs. Homeopathic cures are more effective

the hospitals waiting for a doctor to see them and others were dying in the streets by the cause of them being burnt from the fires or from falling debris. The people that received the least visible damage were the people that received radiation sickness. Radiation sickness causes nausea and vomiting‚ hair loss‚ and severe fatigue‚ which is why the six people that Hersey interviewed saw or personally experienced vomiting in Ason Park and little to low levels of energy by the cause of the fatigue‚

wavelengths of light that the spectrophotometer gives off (Meah‚2013). The level of light transmitted defines the amount of light absorbed‚ for instance‚ the lower the light absorbance the higher the amount of light transmitted. Ultraviolet (UV) light is radiation but the wavelength is shorter than visible light. A solution is a mixture of two or more substances. A stock solution is used to make a variety of other solutions which hold different concentrations; this is done via dilutions (Meah‚ 2013). Diluting

X-radiation (which is composed of X-rays‚ hence the name) falls under electromagnetic radiation. X-rays and gamma rays are sometimes confused‚ but they are different‚ as X-rays are emitted by electrons outside the nucleus whilst gamma rays are produced inside the nucleus. X-rays have extremely small

At the time of death of the organism‚ as a result of decay‚ the amount of radioactive isotope decreases‚ which allows archaeologists to examine the age of excavations. • Radioactivity in many countries is also used for food preservation. The radiation destroys microorganisms and inhibits decay‚ which in consequence prevents poisoning and extends product shelf-life. Fixed irradiated food still has the essential nutrients‚ while leaving it safe for health. • Radioactive methods have been applied

millions of metric tons of coal in a year and polluting the air with harmful carbons‚ nuclear plants use fuel rods as their energy. These rods heat water‚ create steam‚ and generate electricity‚ while not giving off any harmful gases. Atoms and radiation have many applications in agriculture‚ medicine‚ industry and research. They greatly improve the day to day quality of our lives. One interesting use of a radio-active isotope is in reducing insect population. The Sterile Insect Technique (SIT) consists
