Skin Cancer Introduction “Skin cancer is a disease in which malignant cancer cells are found in the outer layers of the skin. Skin cancer is the most common type of cancer in the U.S.‚ affecting more than 1 million people each year.” (Health scout 2001-2006 1). Many people don’t take the risk of skin cancer seriously and continue to lie out in sun regardless of the consequences. The consequences of lying out in the sun can be the development of basal cell carcinoma‚ squamous cell carcinoma‚ and/or

Ultraviolet (UV) rays are an invisible form of radiation so it can pass through the skin and damages the skin cells. Sunburns and tanning are the signs of skin

through a microscope‚ changes are evident in the collagen and elastin structure. Our face‚ hands and chest‚ show signs of premature aging as a result of environmental influences. The main antagonist in prematurely aging skin is exposure to the sun’s ultraviolet radiation‚ which results in a condition known as photo damaged skin. This is evident when you compare the skin or the face‚ neck and hands to the skin or the buttocks or the inner thigh. Although the sun is not the only cause of skin aging it is

Singh Abstract—In the present paper‚ an observation of electromagnetic radiation from base station antennas installed for various communication purposes has been done on the basis of equivalent isotropically radiated power (EIRP) calculations. For this purpose‚ a typical wireless communication site has been selected where GSM‚ CDMA‚ 3G/UMTS and WiMAX antennas are

Introduction Sunburn is damage to the skin that is caused by too much exposure to ultraviolet (UV) rays. Repeated‚ prolonged sun exposure causes early skin aging‚ such as wrinkles and sun spots. It also increases the risk of skin cancer. What are the causes? Sunburn is caused by getting too much UV radiation from the sun. What increases the risk? The following factors may make you more likely to develop this condition: Having light-colored skin (light complexion)‚ skin with many freckles or moles

There are 7 different types of waves in an electromagnetic spectrum; radio waves‚ microwaves‚ infrared waves‚ visible light‚ ultraviolet waves‚ x-rays and gamma rays. Each of these categories contains different type of waves‚ which varies in wavelength and photon energy‚ which is the units in which electromagnetic radiation come in. Figure 1.
