METHOD FOR LOCATION AND SPACING OF ROUND TIMBERS AFFECTED BY RADIONUCLIDES Russian patent published in 2005 - IPC

FIELD: forest industry, applicable in manufacture of sawn timber.

SUBSTANCE: the method consists in fixation of timber for a wholesome peripheral zone, determination of the shape and parameters of the affected layer and division in the longitudinal direction by mutually perpendicular planes in parallel with the generating line tangentially to the inner boundary of the affected layer, separating in this case the affected sections. Then, division is made in the longitudinal direction by mutually perpendicular planes through the lines of contact of the wholesome wood with the remaining affected layer. The timber obtained after removal of the affected layer is divided in the longitudinal direction in parallel with the generating line into the side and central parts, the central part is divided in the longitudinal direction in parallel with the generating line into side parts and the remainder, the side parts are turned relative to each other through 180 deg in the vertical and horizontal planes, the processed surfaces are joined and interconnected in the edge. Joining is accomplished by cementing together with the aid of carpenter elements.

EFFECT: provided location and spacing of round timbers affected by radionuclides.
