| Abstract |
| A necessity need to re-assessment stacking, jamming falling and probability broken cobalt-60 radiation capsules inside storage pool (dry or wet) to prevent bad effects on radiation safety standards inside and outside industrial irradiators. The water of storage pool is contaminated by broken hot capsule where radiation source is changed from close radiation source to very dangerous open radiation source. Using of robotics inside contaminated water of storage pool by cobalt-60 broken capsulate (open source) maintains radiation contaminated for robotics, environment and increasing the needs of developed countries. The work shows a proposed modified design with concrete shielding maze whom has more than one right – angle bend to maintain radiation prohibitive and to determine the smallest radiation exposure rates at the entrance of the proposed maze design with several legs. High standards of radiation safety are maintained by the proposed design through safe containing water treatment plant (deionizer plant) whom is located safely inside the proposed design. Safe design of steel shielding door (swinging or siliding) is attached with proposed design and depending on maze idea too. Electrical control system ( P.L.C) is attached with the steel door design, and whom is located near control panel to maintain radiation safety for environments operation and control during probability of radiation contamination. Monte Carlo calculations have been carried out for the new proposed design that is attached by cobalt-60 industrial irradiator. The three dimensional flux was calculated at different positions from which the gamma volume does was obtained for these positions. |
