Radios and microwaves both use radiation from the electromagnetic spectrum Visible light can be split into a spectrum of colours .. from red through the rainbow colours to violet but visible light is just a small part of the whole electromagnetic spectrum All the different types of electromagnetic waves travel at the same speed through a vacum .. the waves can be orderd by wave length remebered that waves with the shortest wave lengths have the highest frequency and the most energy and the waves

work with radioisotopes due to the safety concerns. There is a risk of radiation when working in close contact with the nuclear reactions. This is because radioisotopes release radiation when they are being produced. Radiation has the power to detach an electron from an atom‚ which can lead to destruction and mutation of cells. Since radiation has this ability‚ and humans are composed of many cells‚ if there is enough radiation exposure‚ it can cause serious harm to health. One more drawback of radioisotopes

we learned that there are 7 types of radiation of the electromagnetic spectrum – gamma rays‚ x-rays‚ ultraviolet‚ visible spectrum‚ infrared‚ microwaves and radio waves. With different wavelengths‚ they each have different properties and uses. Gamma rays are the radiation with the smallest wavelengths – 10-12m to 10-10m – and the most energy and the most danger of any wave in the electromagnetic spectrum. Radiotherapy‚ a treatment the use of high-energy radiation‚ is the most well-known way of how

This half life is long enough for it to be transported form where it is produced to where it needs to be used but it is also short enough to minimise patients exposure to radiation It decays into non-radioactive gas‚ Xenon 131‚ which can easily escape without interfering bodily functions Beta particles can destroy abnormal tissue.

Radiation treatment is the 2nd most common form of cancer treatment‚ next to surgery. The National Cancer Institute estimates that over half of all cancer patients receive radiation treatment sometime over the course of their illness (Radiation Therapy and You 2). It can be used alone to fight cancer or can be used in combination with surgery or chemotherapy. Radiation therapy

terrain. The radioactive material acts as a toxic chemical to which exposure eventually proves harmful or fatal. Radiation is energy that comes from a source and travels through some material or through space. Light‚ heat‚ and sound are types of radiation. Atom-derived radiation is called iodizing radiation because it can produce charged particles (ions) in matter. Ionizing radiation is produced by unstable atoms. Unstable atoms differ from stable atoms because they have an excess of energy or

nuclear fission and fusion. The nuclear fission is the process in which the nuclei of atoms split into two or more fragments under bombardment by neutrons. Nuclear fusion is also called thermonuclear fusion. Nuclear power plants are powered by nuclear radiation using nuclear fission as heat that produces electricity. Nuclear weapons are commonly bombs that cause large destruction. THESIS STATEMENT: “Nuclear results to destructive and serious problems.” SPECIFIC QUESTIONS: 1. What are the effects

Title: Today’s Human Malady: the Nuke plant’s radiation Japan’s nuclear plant in Fukushima‚ northeast of Tokyo‚ had been the latest scare for the past few weeks. It seems that the nuke’s condition is worsening. First‚ it there was just a leak‚ then it turned into a hydrogen explosion and now it is a partial meltdown. People fear the dangers of radiation especially now that it is reported that there are considerably high radiation to Japan’s water and vegetables. It is important that the public

An exercise to decommission the ARE plant finally began in 2003‚ but the work to decontaminate the area is still going on and is estimated to cost RM300 million. The New York Times called it “the largest radiation cleanup yet in the rare earth industry”. ARE was a collaboration between Mitsubishi Chemical Industries Ltd (35%)‚ Beh Minerals (35%)‚ Lembaga Urusan dan Tabung Haji (20%) and several Bumiputera businessmen (10%).
