比释动能
kinetic energy released in material; kerma
bishi由叩neng比释动能(kineticene卿rele胎ed in Irlaterial;ke~)剂量学量之一。1958年，w.c.勒施提出单位质t所释放的动能的概念，称为kerm(kinetiee”e咬万回eaa司卿画t~)，反映不带电粒子辐射与物质相互作用中的能t传递。后又采用比释动能ke~(七杨。ene耳妙花1以曰妇inm川e‘目)，符号为K。比释动能的定义为dE。除以dm所得的商，即 K== dE，/dm式中dE。为不带电粒子在质量为dm的物质中所释放的所有带电粒子的初始动能之和。sI单位为凡一‘(焦耳每千克)，专用单位为仰(戈〔瑞」)。适当选择物质中的比释动能，可以方便地描述不带电粒子的辐射场，例如空气比释动能、组织比释动能等。 (吕维纯徐涌)
