Electromagnetic Radiation and Valence Electrons

Introductory Chemistry, 2e (Tro) Chapter 9 – Electrons in Atoms and the Periodic Table True/False Questions 1) When the elements are arranged in order of increasing number of protons, certain sets of properties recur periodically. 5) A particle of light is called a packet. 9) Ultraviolet light produces suntans and sunburns. 13) Electrons behave like […]

Food Irradiation

Food irradiation has the longest history, more than 40 years, of scientific research and testing of any food technology before approval. Research has been comprehensive, and has included wholesomeness, toxicological, and microbiological evaluation.  Worldwide, 38 countries permit irradiation of food, and more than 28 billion lb of food is irradiated annually in Europe.  It is […]

The Greenhouse Effect – College

The greenhouse effect, as defined in the dictionary, is the effect produced as greenhouse gases allow incoming solar radiation to pass through the Earth’s atmosphere, but prevent most of the outgoing infrared radiation from the surface and lower atmosphere from escaping into outer space. Even though this process occurs naturally and has kept the Earth’s […]

When people sit outside sun bathing the sun’s rays are hitting your body. These rays contain two types of ultra-violet radiation. They are UVA and UVB. These types of UV have different effects on your skin. UVA radiation gives you a tan whereas UVB radiation burns the upper layers of skin, causing sunburn.Melanin is the […]

Burns Case Study

Christenson and Kockrow (2011) states that a burn can be defined as an injury to the tissue which results from thermal, chemical, radiation, or electrical. Thermal burns are caused by a flame, hot fluids or gases, friction, or exposure to extremely cold objects. Flame burns are most often associated with smoke or inhalation injury. Chemical […]

Radiation Therapy

What do cancer, radiation, and technology have in common? The links between the three are quite extraordinary. Cancer is a disease that accounts for 13% of all deaths in the world (Delfino and Day 1). The disease has an impact on patients, friends and their love ones. According to WebMD, radiation is energy that travels […]

The uses and dangers of electromagnetic radiation

The electromagnetic spectrum is a name that scientists gave to different types of radiation when referring to them as a group. Radiation is an energy that spreads out as it goes. For example; visible light is part of that spectrum, the type that comes from a fire or a light, radio waves are another example, […]

Radiation and Pregnancy

Radiation, when unborn children are exposed to it, has deleterious effects on their growth and development which makes it imperative for pregnant mothers to be aware of it and take all possible care in avoiding such exposure. There are many types of radiation: cosmic radiation or the naturally occurring radiation from the sun, terrestrial radiation […]

Therac-25 – College

Therac-25 was designed for radiation therapy for cancer patients that was computerized and was assured that it was “virtually impossible” to give overdose to any patient with it. When a cancer patient is advised for radiation he or she is told that because of the radiation process there will be a certain level of discomfort […]

Black Body Radiation

Blackbody radiation is the electro-magnetic radiation emerging from a small hole in a perfectly black box containing electromagnetic radiation at a high temperature. Scientists were interested in setting standards for the electric and thus measured the distribution of the total electromagnetic energy in a black box among the different wavelengths of the light. But not […]
