Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles; an example of radiation is, electromagnetic radiation.This is a form of radiant energy which travels through space via electromagnetic waves. These waves can be found in the electromagnetic spectrum. This is the range of all possible frequencies of electromagnetic radiation.The range of waves in the electromagnetic spectrum range from radio waves, to gamma rays, the waves in the middle consists of infrared, visible, and ultraviolet waves. In this spectrum frequency and wavelength play a big part on which kind of wave is present. At different frequencies, (the amount of waves per second) and wavelength ,( the length of the wave measured from peak to peak) there are different waves, as these factors change so does the property of the wave. In this essay I will be talking about ultraviolet radiation.
In this diagram you can see the electromagnetic spectrum. It shows the different types of waves. It also goes on to show the wavelength of the waves, as the wave length changes so do the properties of the wave.
The sun emits several types of radiation, most of radiation reaches the earth's surface. Warmth from the sun comes from infrared radiation. While the light and colours we distinguish is caused by visible radiation. Infrared and visible radiation are not harmful under ordinary circumstances. The higher energy part of the spectrum is ultraviolet radiation, a known carcinogen (cancer-causing agent). Both UVA and UVB radiation from the ultraviolet radiation reach the earth's surface. Exposure to either increases your risk of melanoma and other skin cancers. UVC radiation (also part of ultraviolet radi...

...n D has an important use, creating strong bones to aid the body from breaks and fractures, also from diseases like Rickets and Osteomalacia. “Rickets and Osteomalacia are similar diseases, with the latter affecting young children whereas Rickets affects adults. They are both horrible diseases. The effects of both diseases are irreversible, and to contract either of these two diseases a person must suffer from a Vitamin D deficiency.” (Ultraviolet Waves) Therefore, to prevent this, Vitamin D is essential.
Though large amount of ultraviolet radiation is not healthy, however, when considering that it gives out Vitamin D we should be able to stay out in the sun for a little while. Nevertheless, when planning to stay out for a long time while the sun is shining do not forget to protect yourself! The more ultraviolet radiation in your body, the more danger on your skin.

- Intro Very little research has been done on this topic, UV lighting has been known to help mould, but very few test have been done on it. Especially on food moulding, UV lighting has been said to help prevent moulding on objects and things like damp area. Ours will most lightly be one of the first of its kind. Mould is a problem that is or has been experienced by almost every person, especially those living in damp conditions. It can cause several health issues as well as allergic reactions. Research done on this In America, germinal UV lighting has been utilized in public buildings to stop germs growing.... [tags: spores, waves, allergy]

- One late summer evening I was watching the Late Night with Jimmy Fallon. If you are a frequent viewer of Late Night, infomercials account for the majority of the advertising. To this day, I remember Safe Cell Tab being advertised as a sticker-like device that would reduce the risk of cancer when using it with a wireless phone. According to Wikipedia, sixty percent of the world’s population owns a cell phone. There are roughly 6.7 billion people in the world. This means on any given day 4 billion people are exposed to cellular phones.... [tags: Radio Waves]

- Ultraviolet light (UV) is commonly identified as a physical mutagen, initially imposing thymine dimers to occur in Eukaryotic and Prokaryotic DNA.(Lenhart et.al 2012) The effects of Ultraviolet light is also known to induce SOS-responses in Prokaryotic genomes. (Lenhart et.al 2012) By applying UV light at different time intervals, the results show DNA topology efficiency of each strain and the overall repair efficiency in which was compared. The plasmid was exposed to 30 seconds of UV light in 10 second intervals, with a control of 0 seconds of UV-exposure.... [tags: DNA, Bacteria, Ultraviolet, Escherichia coli]

- Sunblock Opposed to Sunscreen Through the depleting ozone layer and increasing levels of ultraviolet radiation within our atmosphere, skin cancer has risen as one of the major problems within contemporary society. Unfortunately, UV rays increase the risk of obtaining skin cancer since they permanently alter the DNA structure within our cells, creating a vast array of mutated cells. Research has shown that melanoma is considered the most serious type of skin cancer due to the development of dark spots on the skin, which develop in basal cells at the base of the epidermis caused by the exposure of ultraviolet rays....

- Many people, around the world, use cellular or mobile phones in their everyday life. With the amount of time spent on a cellular phone increasing, so is the concern that these mobile devices, in which we so heavily depend, are now giving us cancer. There is no consistent evidence that connects the use of these wireless devices to any specific type of cancer. Additionally, more research is needed to examine the technology of cellular phones and how people use them. Technology and use habits are constantly changing....

- Climate change endangers a human health in many ways, including weather, wildfire, and air quality. Environmental consequences of climate change, such as extreme heat waves, rising sea-levels changes in precipitation resulting in flood and droughts, intense hurricanes, and degraded air quality, affects directly and indirectly the physical, social, and psychological health of humans. Rising global temperatures have been caused by the changes in weather and climate, but humans are responsible for the recent climate change and endangers to their health....

- Effects of Microwave Radiation On The Human Body I am going to research the effects of microwave radiation on the human body mainly from mobile phones. I am going to collect a wide range of information from a number of reliable and different sources. To research the effects of microwave radiation on the human body I am going to look at five different sources. Firstly I am going to look at the Internet to find two sources of information one from a scientific organisation and one from a mobile phone manufacturer.... [tags: Papers]

- Losing sleep produces significant consequences to the overall health of a body. There have been numerous tragedies in history linked to errors by tired, sleep-deprived humans. Two major events caused by fatigue were the Exxon Valdez Oil Spill and the NASA Challenger shuttle explosion. The horrendous outcomes of these events are why humans need a better understanding of how sleep affects their quality of life. (NSF) When sleep is lost, there may be detrimental effects to your health and the well-being of others.... [tags: health, REM, NREM, brain, negative effects]

- The Effect of Increased Ultraviolet Radiation on Marine Ecosystems Abstract Nearly 80 percent of the Earth's surface is covered with water, nearly all of it being in the form of oceans. Therefore, any environmental changes that are sensed on a global scale are certainly expressed in aquatic ecosystems. The purpose of this paper is to explore the nature by which one aspect of the changing environment, ultraviolet radiation, affects the sensitive balance of the oceans. Specifically, the focus will be on the relationship between increasing ultraviolet radiation and the survival of phytoplankton, fish, and other aquatic animals.... [tags: Geology]

- INERNATIONAL BACCALAUREATE SUBSIDIARY LEVEL WAVES SUMMARY 4.1 Travelling wave characteristics A medium is a material through which a wave passes. When a wave passes, each part of the medium moves away from its normal position and then returns. This is called an oscillation. Oscillations within the medium are slight movements either side of the normal position. The wave motion is the disturbance that passes through the medium. A wave pulse causes the medium to have one oscillation. A continuous travelling wave causes the medium to keep oscillating.... [tags: essays research papers]
