如果光束的强度和物体向太阳投射的面积是已知的，那么入射到物体表面上的太阳能的量就可以计算出来。本文介绍了一种摄影方法，它已被开发用于测量在垂直于太阳光线的方向上投影的站立姿势下的身体面积。25名男性和25名女性受试者进行了研究，其表面积范围为1·30 m2至2·20 m2。有效辐射面积与身体的表面积有关，并且这种关系基本上与身体的尺寸和形状无关。已经发现了一个方程，它使辐射面积计算的任何角度的高度和方向的身体相对于太阳的方向。
The amount of solar energy incident upon the body surface can be calculated if the intensity of the beam and the area of the body projected sunwards are known. A photographic method is described which has been developed for the measurement of the areas of the body in the standing posture which are projected in a direction normal to the solar rays. Twenty-five male and 25 female subjects were studied, whose surface areas ranged from 1·30 m2 to 2·20 m2. The effective radiating areas are related to the surface area of the body and this relationship is substantially independent of body size and shape. An equation has been found which enables the radiating area to be computed for any angle of altitude and orientation of the body with respect to the direction of the sun.
