Measurement and analysis of dose uniformity ratio for pile-up irradiation in static state in irradiation room
The quality of three irradiation techniques for five irradiated products has been studied using the measurement of dose ununiformity in product box irradiated. The results were as follows: 1) The range of dose ununiformity was from 1.36 to 1.67 with changing the position from the top to the bottom a...

| Summary: | The quality of three irradiation techniques for five irradiated products has been studied using the measurement of dose ununiformity in product box irradiated. The results were as follows: 1) The range of dose ununiformity was from 1.36 to 1.67 with changing the position from the top to the bottom and from the front to the back and it didn't exceeded the dose ununiformity limitation (U<2). This technique can been used to production.2) The dose ununiformity of single face irradiation was 2.67. It exceeded the limitation described, so which can not be used to production.3) The dose ununiformity of single face irradiation in the back rank (two products) were 3.25 and 3.69 respectively, also exceeded the limitation described and can not be used to production. But it can be used as assistant irradiation method for increasing the utilization efficiency of <sup>60</sup>Co. |
