radio waves‚ extremely low frequency waves etc. are all packed in the radiation that emanates from the sun. From time immemorial human race knew that the ultimate source of energy for the earth is from the sun. Modern science has established that this energy is quantifiable‚ for better understanding‚ as electromagnetic radiation‚ EMR. Radiations

Ionizing radiation is radiation that can damage DNA and increase the risk of cancer tremendously. This form of radiation involves high-energy photons being absorbed by the body and penetrating the DNA (8). MRI differs from this because it uses non-ionizing radiation in the form of magnetic fields and radio waves and this type of radiation has not been linked to cancer yet. However‚ it is notable that most non-ionizing radiation is heat and patients run the risk of

early it has been detected. One method of treatment for cancer is Radiation therapy (Radiotherapy). This is the medical use of ionizing radiation to control or kill these malignant cells. However‚ there is doubt among society about the use of radiotherapy. This is mainly because some long-term side effects include the growth of scar tissue‚ infertility and damage to other areas of the body‚ depending on the location of the radiation treatment. Another major reason for doubting this treatment is because

Tips on Radiation Exposure CINCINNATI‚ Oct. 2‚ 2012 /PRNewswire-USNewswire/ -- With millions of X-rays performed on children every year‚ kids are more likely to receive X-rays than any other type of imaging exam. A new education campaign seeks to equip parents with the knowledge they need to make informed decisions about their kids and X-rays. Through a series of online teaching materials aimed at parents and medical professionals‚ Image Gently’s "Back to Basics" campaign promotes radiation protection

radioisotopes has increased our knowledge of biological processes and chemical reactions in humans and plants. New technologies: Geiger counter and Autoradiography. A Geiger counter is a type of particle detector that measures ionizing radiation. It is used as a handheld radiation survey instrument. Autoradiography is a technique used to trace the movements of certain substances around plants. The movement of the radioisotope can be traced by taking an autoradiograph. An autoradiograph is produced

contributed to earlier cancer detection in women. Dr. Wilhelm Conrad Roentgen discovered x-rays while working with a Crookes tube in his laboratory on November 8‚ 1895. Eighteen years later mammography got its rudimentary beginnings due to these ionizing x-rays. In 1913‚ Berlin Albert Soloman‚ a German surgeon‚ was among the first to discover that breast cancer could be radiographed. In a 1927 medical textbook the first instance of a radiograph of a living person’s breast taken by Otto Kleinschmidt

Ultrasonography consist of the use of sound waves and is not a form of ionizing radiation. There have been no news of recognized conflicting fetal effects for diagnostic ultrasonography measures‚ as well as duplex Doppler imaging.

The Effect of Nuclear Energy on Human * As we all know‚ nuclear energy is a non-renewable energy. The science of atomic radiation‚ atomic change and nuclear fission was developed from 1895 to 1945‚ much of it in the last six of those years (WMA‚ 2010). Since then human have begun expanding their research on nuclear energy and sadly during year 1939 to year 1949‚ nuclear energy was only used for creating atomic bomb by many of the countries back then such as Japan‚ Germany‚ United States of

The ionizing radiation is a minute quantity of americium 241‚ which is a source of alpha particles. The radiation passes through the ionization chamber and the air-filled space between the two electrodes. Smoke that enters the chamber will absorb the alpha particles and will reduce the ionization
