Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry. Shielding against gamma rays is essential because theycan cause diseases to skin or blood, eye disorders and cancers. What are gamma emitters? Gamma radiation isoften used to kill li...
摘要: Using a Wilson cloud chamber in a magnetic field of 1000 gauss we have studied the spectrum of recoil electrons produced by the gamma-rays from boron bombarded with deutons, and have found it to consist of components of at least five different energies....

Gamma and x-rays are bothelectromagnetic radiationbut differ in their origin. As stated earlier,gamma raysoriginate in the nucleus of an atom, while x-rays arise from sources outside the nucleus. Becausegamma rayspossess more energy that alpha andbeta particles, they are able to penetrate much...
These results are discussed, with an emphasis on membrane-damage-mediated apoptotic death with relevance to improvement of cancer radiotherapy. 展开 关键词: Apoptosis Cell Membrane Gamma Rays Oxidative Stress 脱噬作用 细胞膜 γ射线 氧化性应激
The gamma-ray source uses a directed beam of gamma rays with variable cross section. The device is equipped with a shielding container (head) made of lead, tungsten, or uranium, which holds the radiation source (usually 60Co, less frequently 137Cs; radium was formerly used). A port in ...
Gamma rays are ionising radiation (IR) and are widely used in radiotherapy to treat various cancers. Radiotherapy confers a survival benefit by destroying cancer cells by depositing high-energy particles on the cancer tissues and has been driven by persistent technological advances [1]. Over recent...
