最大允许注量是光子场辐射监测中的一个实用概念。实际上，这是用于监测中子场的概念。在一个大的能量范围内所需的响应函数的设计仪器的实用性进行检查。应用腔体电离理论研究了气体填充、壁材、腔体尺寸和壁厚对响应函数的影响，从而确定了电离室设计的最佳参数。一个实验室的参数接近最佳已建成和它的响应相比，从空腔电离理论计算的响应。它的结论是，它是可以设计的仪器，其能量响应如下的最大允许的注量。本文中的方法和数据将有助于在修改国家法规时出现的任何必要的设计变更。
The maximun permissible fluence is proposed as a practical concept in radiological monitoring of photon fields. It is virtually this concept that is used for monitoring neutron fields. The practicability of designing instruments with a required response function over a large energy range is examined. Cavity isonisation theory is employed to examine the effect of gas filling, wall material, chamber size and wall thickness on response function and the optimum parameters for the design of an ionisation chamber are thus identified. An experimental chamber of parameters close to the optimum has been constructed and its response compared with the response calculated from cavity ionisation theory. It is concluded that it is possible to design an instrument, the energy response of which follows the maximum permissible fluence. The approach and data in this paper will facilitate any necessary design changes which would arise in the event of national regulation being modified.
