We depend on electromagnetic energy every moment of our lives, from watching tv to microwaving our food, without it our world would not be the same. Electromagnetic energy travels in waves, and has a very large range from long radio waves to very short gamma rays called the electromagnetic spectrum. The electromagnetic spectrum is the distribution of electromagnetic radiation according to energy, frequency or wavelength. From radio waves to gamma rays there are 7 types of lights most not visible to the naked eye in the electromagnetic spectrum which covers a wide range of wavelengths and photon energies. Different objects and living thing detect different proportions of the spectrum, the human eye can only detect visible light, radios can detect a different portion of the spectrum, and an x-ray machine uses another portion. To study the universe NASA's uses a scientific instruments which can detect the full range of the electromagnetic spectrum.
Each ray in the spectrum have different characteristics and features. Gamma rays, along with 2 others are "ionizing," meaning these waves have such a high level of energy that they can knock electrons out of atoms. Exposure to these highly energized waves can reshape atoms and molecules and cause damage to cells in natural, untouched forms and matter. This is where the separation of the advantages and dis advantages of ionizing waves occur. These changes to cells can be helpful, as when radiation is used to kill cancer cells, yet if not taken care of seriously it can be highly dangerous to the lives of us humans. Out of the electromagnetic spectrum Gamma rays hold the smallest wave length of 10 to the power of 10-10 to the power of 12. In electromagnetic radiation the wave’s frequency is ...

...n anyway. Thus gamma rays have a positive effect on us through the environment. This process is also implemented into the benefits of economies, as it will lead to saving money on not only crops yet other consumer goods, by keeping them fresh and safe through an efficient process.
Overall gamma rays contribute greatly to our health and our understanding of our universe. Its high level of energy leads to many medical benefits when used wisely and carefully, and even though it can cause many dangerous and harmful reactions, we have developed a strong understanding of the photon so that we know how to effectively and efficiently use it without causing harm. Our understanding of the photon has led to curing medical conditions, understanding specific characteristics and fields of our universe and creating a financially efficient and safe system of economic production.
The light released by the sun consists of three frequency bands of radiation: infrared, visible and ultraviolet. Out of the three frequency bands, the ultraviolet light is damaging to most humans. Ultraviolet (UV) radiation divided into three categories: UVA, UVB, and UVC. UVA radiation passes through the skin without burning the surface layers. These rays can penetrate to a depth of 0.04 inches and causes damage to cell membranes and the immune system. UVA radiation has been linked to skin cancer, early aging and wrinkling of the skin. UVB radiation is responsible for the painful red burn people get after a long period of exposure to the sun. UVB rays also cause skin cancer and damage to the cornea and lens of the eye. The third category, UVC radiation, is generally absorbed by the Earth’s atmosphere and is not considered harmful.
Cosmic rays are to scientists much like photons are to astronomers. Just as astronomers use light (or photons) to view our galaxy and beyond, scientists use cosmic rays to infer useful properties about our galaxy. In fact, cosmic rays offer one of the few ways in which scientists can actually sample real matter outside of our solar system. By identifying the various nuclei that are dispersed throughout our Galaxy, scientists hope to unravel the mechanisms that actually produce these nuclei -- from stellar nucleosynthesis to nucleosynthesis within supernovae to nuclear fragmentation. Just think, the iron in your blood came from a supernova billions of years ago in our solar neighborhood! To measure cosmic rays directly, before they have been slowed down and broken up by the atmosphere, research is carried out by instruments carried on spacecraft and high altitude balloons, using particle detectors similar to those used in nuclear and high energy physics experiments. However, there are other means of studying cosmic rays that reveal new information.. An analysis of cosmic rays using a cloud chamber reveals a connection between frequency and altitude.
This paper talks about the gamma-ray explosions that occur in the universe and its effect if it were to occur close to the earth’s surface. The most energetic explosions to be recorded in the universe are the gamma ray bursts. Gamma ray bursts forms a representation of the events that occur in the cosmos due to its large luminosity that has been detected to approximately z-8.3. This has offered an exciting experience in the study and research of the astrophysics in its extreme condition. The paper focuses on the study revolving around the long gamma ray burst and also the galaxies that form their hosts. The long gamma ray burst have long duration that is more than few seconds and the hypothesis supporting its development states that it develops from the massive stars death. The paper also tries to understand the effect of the gamma ray bursts and how they are related to the redshift distributions in the universe. It tries to analyses the different types of wavelengths that gamma ray burst generates after the collision or merging of bodies in the universe. It explains how recent development in technology has brought man closer in studying gamma ray burst in depth and because of the abilities of the technology, man can understand the different wavelengths generated. Finally, the paper talks of the possibility of gamma ray burst happening closer to the earth’s atmosphere as it happened millions of years back. It tries to look into the impact on the ecosystem and the survival of animals if such a phenomena occurring was to repeat itself closer to the planet earth’s environment.
There are essentially three main types of cancer treatments; surgery, chemotherapy, and radiation. Surgery allows doctors to effectively remove tumors from a clear plane. Chemotherapy uses drugs to treat the tumor; but often the drugs affect other healthy cells in the process. Using radiation as a treatment can be either precise or vague. Many health stigmas can come from the vague forms of radiation or conventional radiation therapy. Conventional radiation treats both the unhealthy and healthy cells, therefore exposing healthy cells to harmful radiation (Radiation Oncology, 2011, p.6). When healthy cells are exposed to gamma radiation they are also exposed to ionizing radiation. The ionization can cause “breakage of chemical bonds or oxidization (addition of oxygen atoms)” in a cell; the main impact of this is on a cell’s DNA, if two strands of DNA break it can result in “mutations, chromosome aberrations, ...
The Electro Magnetic Spectrum Radio Waves Radio waves are made by various types of transmitter, depending on the wavelength. They are also given off by stars, sparks and lightning, which is why you hear interference on your radio in a thunderstorm. Radio waves are the lowest frequencies in the electromagnetic spectrum, and are used mainly for communications. Radio waves are divided into:- [IMAGE]Long Wave, around 1~2 km in wavelength. The radio station "Atlantic 252" broadcasts here.
Nuclear energy is used today for energy supply and about 15% of the world’s energy comes from nuclear power plants some forms of medicine such as nuclear medicine rely solely on nuclear technology. This technology was developed through the process of creating the first atomic bomb and would not exist if not for the advancements made during the Manhattan project.
In conclusion, there are different opinions on the issue of the use of nuclear energy. Nuclear energy is only one of many energy options. Nuclear power can decrease pollution to the environment because it does not produce harming gases like other plants do. However, there are also drawbacks that can influences human health by emitting radioactive substances. Thus, all parties should make a deeper research and analysis based on the argument to decide the use of nuclear energy as a safe and cost effective source of energy.
Radiation has always been in everyday life even before Roentgen discovered x-ray. The mountains give off natural radiation, other forms of radiation are coal burning power plants, x-rays from a TV, and an airplane ride. The average dose from background radiation is about 360 mrem every year. There are two types of radiation, nonionizing and ionizing radiation. Examples of nonionizing radiation are microwaves and radio waves broadcasting. Ionizing radiation refers to gamma and x-rays. Ionizing radiation means that the rays are able to remove an electron from the atom then ions can be formed. The ions can cause damage when reacting with other atoms. Cells are able to be repaired if low dose are received. However, if cells get a high dose, the cells will be damaged or possibly die. If the cell is damaged permanently then it is referred to as a mutated cell.
If one is affected by cancer, there are treatments to help take away this illness affecting their body. This essay is about a specific type of treatment for cancer, radiation therapy. There are different types of forms of particles for radiation, for example, protons and waves like x-rays and visible light. These types of radiations are grouped on how much energy they contain because they can cause different effects. A low type of energy radiation can be radio waves and heat, also known as non-ionizing radiation.
... our daily life and has lot of consequences. For example, we know that black surfaces absorb more thermal energy and reflect less thermal energy. Similarly, the shiny surfaces absorb less energy and reflect more energy. This is the main reason that a black car parked in the sun will heat more as compare to the white car. The process of radiation is also used in the field of medicine. Thermography is an interesting use of the radiation in the medicine. Thermograph is a scan of the picture of the body and is a photograph according to the intensity of the radiation at different places. Since diseased parts are usually more hot so thermograph shows prominent white and red spots which helps the doctors to diagnose the disease.
Radiation exposure can affect children as well an children have the risk of being the most harmfully effected by radiation because their body absorbs substances differently also their bodies can or are more likely to get certain kinds of cancers from too much exposure, “they are also closer to the ground, where radioactive fallouts settle.”
The History of Microwave Radiation, its Common Uses, and its Effects on Human Anatomy Overview Beyond our earthbound lives exists a firmament of endless wonder, filled with waves and particles unfathomable to the human eye. Ultraviolet, infrared, and radio waves permeate our atmosphere from beyond our space and time. These include microwaves. From their origins at the Big Bang, the pulses of these waves can still be observed to this day.
The energy in ionizing radiation can cause chemical changes in the the cells that can lead to damaging them. Most of the cells can either permanently or temporarily become abnormal or they can just die. Radiation can cause cancer by damaging the DNA in the body. The damage of the cells can also depend on how long the organs are exposed (environmental protection agency, 2017, unknown). If someone has many exposures at one time that radiation in the body keeps adding on. As well as if its only a little bit of exposure in on day and years later you get exposed again it keeps adding on the radiation will never leave the body. Having radiation in your body doesn’t affect you right away but as you get older it starts to show and you feel it. Chronic exposure is when someone is exposed many time for long periods. When this happens the type of effects it will carry is having harmful generic change, cancer, tumors, and even cataracts. Partial health effects can also depend on if it was internal or external exposure. Internal exposure is when either by drinking, breathing, eating and even an injection cause radiation to get inside your body. External exposure is when taking an x-ray out of your body and letting it go through letting all the energy go as it goes in (environmental protection agency, 2017, unknown). In the dental world radiation gets into the patients when we take x-rays on there teeth. In order to avoid to much radiation on them we put a lead apron on them and make sure to cover their thyroid which is the most common way of getting cancer when taking an x-ray. When we take the x-ray we stand behind a wall at least 6 feet away to avoid ourself from getting
Scientists and engineers have been able to enhance our lifestyles by understanding and using the Laws, Concepts and Principles of Optics and how they are applied in Optical Instruments. The key concepts are:
Electromagnetic radiation is energy that flows through free space. Electromagnetic radiation comes in a list of energies known as the electromagnetic spectrum. Electromagnetic spectrum is the complete range of the different wavelength of electromagnetic radiation. It consists of light, radio waves, visible light, infrared waves, ultraviolet light, x-rays, microwaves and gamma rays.
