Abstract
Objective:
To study the dose distribution in human body and dose parameters under various exposure conditions.
Methods:
In consideration of various factors, we calculated the dose distributions in human body by tissue-air ratio. Then dosimetric parameters were obtained. The calculation was verified by experiments using tissue equivalent anthropomophic phantom.
Results:
The more homogeneous the dose distribution was, the stem cell dose was closer to the average dose. Stem cell dose could be larger than average dose. The difference between stem cell dose calculated and that by experiments was less than 5%.
Conclusion:
The calculation method and the program were reliable. The computer program has been applied in radiation accidents.
