Medical Physics is an interdisciplinary field that applies concepts and laws of physics in medical practices. Currently, one of its main applications is the use of ionizing radiation in the treatment of oncological diseases. Due to its wide use and highly dangerous, many of radioprotection procedures should be adopted with the objective of protecting human beings from harmful effects of radiation. Thus, you can better enjoy the benefits that the practice can offer. The methodology proposed by the National Council on Radiation Protection 151 (NCRP 151), relates technical information necessary to Structural Shielding Design and Evaluation for Megavoltage X- and Gamma- Ray Radiotherapy Facilities. However, many parameters used to calculate the shield are based on estimates only, and it is an international standard that may not be adequate to the Brazilian reality. Thus, the central idea of this study is the collection of data from the routine of the Radiotherapy Service of the Real e Benemérita Associação Portuguesa de Beneficência, in particular equipment cobalt therapy Theratron 780 (Atomic Energy of Canada Ltd.) and the linear accelerator Varian Clinac 2100C for measurement of workload, number of patients, fields, and dose factors to determine the best use of barrier protection. Furthermore, this work features a profile of radiotherapy treatments carried out closer to the Brazilian reality

Welsch (Projektbearbeiter): Definition des Begriffes 'reaktionär' und dessen positive Umdeutung im konservativen Sinne: Reaktionär ist a) wer glaubt, daß dem Vaterland Einheit, Ordnung und Kraft not tut; b) wer glaubt, daß die Aufhetzung der arbeitenden Klassen durch "Verbreitung communistischer Grundsätze" dem Vaterland abträglich ist; c) wer es ablehnt, Soldaten und Landwehrmänner in ihrer Treue zum Staat wankend zu machen; d) wer es ablehnt, 'Wühler' im Trüben fischen zu lassen. Warnung, die Grundfesten des Vaterlandes durch 'Anarchie' zu unterwühlen und es zur Beute der "Selbstsucht seiner entarteten Söhne" sowie "der raubgierigen Horden des Auslandes" werden zu lassen
