The measurement of ionizing radiation is sometimes expressed as being a rate of counts per unit time as registered by a radiation monitoring instrument, for which counts per minute (cpm) and counts per second (cps) are commonly used quantities. Count rate measurements are associated with the detection of particles, such as alpha particles and beta particles. However, for gamma ray and X-ray dose measurements a unit such as the sievert is normally used.

  • Counts per second (dt. Zählschritte oder Zählimpulse pro Sekunde), kurz cps, ist eine Maßeinheit für die Zählrate (die Anzahl von zeitlich getrennten einzelnen Ereignissen pro Zeitspanne, in der sie gezählt werden). Analog zur Einheit Counts per second ist die Einheit Counts per minute (cpm) definiert. (de)
  • Le coup par seconde, ou choc par seconde, de symbole c/s ou cps, est une unité de mesure d'émissions radioactives. Ces émissions se mesurent avec un ictomètre. Une valeur en coups par seconde représentent une mesure brute dont le niveau exact dépend à la fois de l'appareil utilisé et du contexte d'utilisation. Elle doit être interprétée afin d'être convertie en un niveau d'irradiation précis. (fr)
  • 每分钟计数(英語:Counts per minute,符号:CPM),表示单位时间1分钟内放射性检测仪器(如盖革计数器)测到的电离事件的计数。CPM不属于国际单位制。而CPS表示1秒钟内的电离事件的计数。 CPM一般用于表示某种粒子的度量单位,如阿尔法粒子、贝塔粒子。而伽玛射线或X射线的计量单位一般用希沃特。 放射性计数率(count rate)不同于放射性剂量率(dose rate),二者需要换算。转换计算依赖于放射性能量级别、被检测的放射性类别、以及探测器的放射性特征。电离室可以测量放射性剂量,而盖革计数器可以测量放射性计数。这需要到计量院用已知放射性强度的辐射源标定盖革计数器。标定后会给出某一特定能量伽马射线(如钴60)的探测效率K。计算时用计数器读数M除以探测效率K即为微希沃特每小时。需注意探测效率的单位。 (zh)

  • The measurement of ionizing radiation is sometimes expressed as being a rate of counts per unit time as registered by a radiation monitoring instrument, for which counts per minute (cpm) and counts per second (cps) are commonly used quantities. Count rate measurements are associated with the detection of particles, such as alpha particles and beta particles. However, for gamma ray and X-ray dose measurements a unit such as the sievert is normally used. Both cpm and cps are the rate of detection events registered by the measuring instrument, not the rate of emission from the source of radiation. For radioactive decay measurements it must not be confused with disintegrations per unit time (dpm), which represents the rate of atomic disintegration events at the source of the radiation. (en)
