Radiation Measurements by Means of a Radiometer,
Abstract
The principal parts of a radiometer (detector, diaphragms, and optics) are briefly described and a series of formulas are given to measure the stream of radiation as to distance from the source, angle of emission, and intensity. Thermocouples, bolometers, and phototubes are described as radiation detectors. The radiometer developed at the Prague Thermomechanics Institute is described in detail, with its copper-constantan thermocouple as sensor, copper block, and perforated constantan foil defined by a series of formulas. The process of calibrating this radiometer by means of an absolute black body is described, and indicated a ratio of equivalent 1.3 between real and theoretic values for sensitivity to electromotive force.
