before the age of 35 increase their risk for basal or squamous skin cancer by 75 percent. Prevention from getting these types of skin cancer include applying sunscreen whenever under harsh sun conditions and not exposing skin to man-made ultraviolet radiation sources‚ for example‚ tanning beds. When in the developing years‚ the skin is more prone to being damaged‚ which is why it is important to prevent teens and young adults from excessive UV exposure. If youths are prohibited from the tanning bed industry

patients and healthcare professionals. But‚ that’s not 100% true. For health care providers who work in the radiology field they are continuously getting exposed to radiation and have to be very cautious with how much they receive. “Radiology is the science dealing with X-rays and other high-energy radiation‚ especially the use of such radiation for the diagnosis and treatment of disease.” In 1895 Röntgen discovered the X-ray‚ instantly people put much interest into the machine. Little did Röntgen know

phones transmit and receive Radio Frequency (RF) signals in order to communicate. The RF signals from [cell] phones fall within the microwave part of the electromagnetic spectrum. This radiation is also referred to as microwave radiation or electromagnetic radiation. In short: Cell phones use microwave radiation to communicate.

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

Reciprocity theorem: Many antenna properties are the same for both transmitting and receiving. It is often easier to calculate the gain of a transmitting antenna than the collecting area of a receiving antenna‚ and it is often easier

Electromagnetic spectrum is just a name for the range of ALL possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object has a different meaning‚ and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. The spectrum extends from below the low frequencies used for modern radio‚ to gamma radiation at the short-wavelength (or high-frequency) end‚ therefore covering wavelength for thousands of

MEN 510 Energy Conversion Assignment 2 Proton Therapy Presented to: Dr. Walid Assaf By: Farid Akiki 20082191 Semester: Fall 2012 Proton Therapy Proton therapy (also called proton beam therapy) is a type of radiation treatment that uses protons rather than x-rays to treat cancer. A proton is a positively charged particle that is part of an atom‚ the basic unit of all chemical elements‚ such as hydrogen or oxygen. At high energy‚ protons can destroy cancer cells.
