1964 / 1-2. szám - L. LEHOCZKY-P. SOÓS: Design of an Outdoor Radiation (Gamma) Field

3 DESIGN OF AN OUTDOOR RADIATION (GAMMA) FIELD The applied radioactive source (Cobalt 60 having an activity of 250 Curie) was produced in the USA. The circular irradiation field has a radius of 40 m. it is encompassed by a mound of trapezoidal cross section having a bot­tom-width of 6 m. The height of same near the neighbouring houses is 5 m, while 3.5 m along the other sections. The cross section of the container is presented in Fig. 4.
