A broad variety of biolocical parameters were investigated. Number and ration of erythrocyte and leucocyte in periperal blood samples; differentiation between lymphocytes and granulocytes. Determination of body weight and organ/bone weight (spleen, thymus, adrenal glands, and femur). Estimation of nucleated cells in organs. Determination of DNA synthesis in cells of the cornea as well as light and electron micoscopic investigation of this tissue.
None of the investigated parameters was significantly affected. Therefore the practical use of this radar device was recommended with cautions about long-term exposure on eyes.
