A lot of cancers do not have specific or noticeable signs. Therefore‚ prevention and correct screenings for cancer are of the greatest relevance. A lot of cancer screenings are normally age-specific. A primary care physician must suggest the correct screenings for cancer during yearly check-ups. There are several risk factors that are known to have an effect on and increase the associated risk of cancer. Healthcare experts advised that individuals take steps to manage their risk by making necessary

dangerous. They emit a type of radiation called radio frequency (RF) that has been shown to damage genetic material in blood cells‚ which can cause cancer. Radio frequency energy is a form of electromagnetic radiation. Electromagnetic radiation are categorized into two type: ionizing and non-ionizing. Ionizing radiation are found in x-rays‚ cosmic rays‚ and radon. Non-ionizing radiations are found in radio frequency and extremely low-frequency or power frequency. Ionizing radiation increase the risk of cancer

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

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
