摘要

Purpose

To obtain more accurate exposure doses to occupational personnel in particle accelerator radiation environment.

Methods

The Monte Carlo simulations are adopted together with developed dose estimation algorithm.

Results

A dose estimation algorithm based on two exposure approaches: stationary dose and dynamic dose, is developed in this work, thus allowing detailed and accurate calculations of individual doses during interventions. Take Ultrafast Transient Facility as an example, prompt dose and residual dose induced exposure are estimated using the FLUKA code.

Conclusion

Calculations of doses exposure based on trajectory planning from two different radiation sources are conducted. A total of 2.10 μSv and 6.17 μSv from operation and cooling time are obtained.
