As another important difference between ionizing and non ionising radiation, ionising radiation can emit electrons or other particles from atoms when they collide while non ionising radiation cannot emit partic
Non ionizing radiations do not emit particles from other materials, because their energy is lower. However, they carry enough energy to excite electrons from ground level to higher levels. They are electromagnetic radiation, thus have electric and magnetic field components parallel to each other and...

Our electronic devices emit radio waves, which are a low frequency, non-ionizing radiation. This in contrast to higher frequency, ionizing radiation such as X-rays and gamma rays, that can damage DNA over long exposure. Radio wave frequencies range from 800MHz (800,000Hz) to 2GHZ (2.5 bill...
into accountthedifference inmembership between the two organizations. unesdoc.unesco.org unesdoc.unesco.org 总干事希望根据上述建议的会费分摊比额表,将教科文组织 2004 年和 2005 年的这一 比额表列入本文件附件 I,其中包括考虑到两个组织之间在会员国组成方面的差别而作的适当调整。
this document provides little clue as to the distinction between, say, single and double precision arithmetic, other than to require that the set of single precision values be a subset of the set of double precision values. One may get t... SAFD Cid,RBK Dewar,AFD Cid - New York Universit...
non-CR digital radiography, unless perhaps one considers the charges prior to readout by the semiconductor arrays. There was a latent image in selenium drum DR systems, in the form of unsatisfied charges remaining after exposure to ionizing radiation. There is n...
Both anMRAandMRIare painless and typically noninvasive diagnostic imaging tools. Doctors may use one of these to view bones, tissues, organs, blood vessels or arteries inside the body. Since they’re so closely related, it can be challenging for patients to understand the difference between MRI...
James Chadwick discovered the neutron. The experiment that lead to the discovery was bombarding beryllium metal with alpha particles. They observed that, after bombarding, a non-ionizing, very penetrating radiation emitted from Beryllium. When this radiation was allowed to hit with a paraffin wax blo...
Translocation is a type of chromosomal rearrangement that occurs between non-homologous chromosomes. Broken segments are exchanged between two nonhomologous chromosomes. It creates two chromosomes that are genetically different from the native chromosomes. Reciprocal and Robertsonian are two types of transloca...
