Question

1. Why is the study of Radiation Biology and Biophysics essential to the fields of Medical Physics and Nuclear Medicine? How might it be important to other fields such as Astronomy, Anthropology, Biology, Geology and Forensic Science? 2. What is greatest source of background radiation exposure to all humans in the United States and how does it primarily enter the body inhalation, food, external (skin), etc.). How does this background exposure compare proportionately to exposure to medical sources of radiation such as nuclear medical and medical X-ray exposure?

Answer 1

*The relation between Radiation Biology and Biophysics with the Medical physics f Nuclear Medicine is alway connected to eachother. The medical physics in early centuries were dependent on the radiation application and at present still the physics is depends upon application of radiation. The diagnosis to the raphy enerywhere Radiation biology and Medical physical is involved. " The ure of cancer has been, and continues to be, the major driving force of medical physics. The main outcome has been the development 06 a variety of therapeutic methods based on the use of rodià tion of known as radiotherapy The use of Radiation Biology and biophysics important in fields such as Astronomy, Biology or forensic science as the radition some of the radiation (IR) anises from thermal vibrations of radiation that have Yonger wavelength than visible light. The aniount of thermal IR radiation emitted by an abject is avouated with the temperature of the object and hence helps in forensic science.

* radiation The greatest source of background exposure to all human in the United States is the Radon. Although it is an colorless, odorless gas that is generally formed from the breakelown of radioactive elements in the ground. Radons levels can be found wually higher inside buildings & homes whose levels are closer to the basements. It goes into the body through inhalation as it is a gas and while breathing it centers the body. These gases are as much as harmful as the exposure to radiation or the X-Rays. These gases cause the same harmful effects on human body as the radiation does.
