[en] Radiometric gage for measuring density of solid products made, for example, with the use of powder metallurgy method is proposed. The densimeter contains coaxially mounted collimated γ-sourse and ionizing radiation detector, unit of product fixation in the translucence zone, provided with the compensation block. To improve the accuracy of density measurements of products with thickness, varying within the limits of technologic tolerances, the compensation block is produced in the form of two supports, one of which is stationary, the other one is mobile and stiffly bound with the compensating body, entering under ionizing radiation flux and providing the transluced volume constancy. The device allows to reduce the measurement error and to bring down expenditures on the density control
