Abstract
A study was conducted to dose analysis of human body organs of ORNL mathematical phantom as a personnel in radiation field of the 2.5 kJ plasma focus device. The dose calculations were performed for 108 fusion neutrons per shot (with energy of 2.45 MeV) from deuterium and deuterium fusion (D–D) using Monte Carlo MCNP code. Based on the results, assuming 2600 shots/year (10 shots/day), equivalent and effective dose obtained by operator in different distances from plasma focus device is less than the determined yearly working dose which is assumed 20 mSv/year. The calculations showed that for working in close distances to PF (distance about 50 cm) or in the PF radiation field with more than 10 shots/day, Polyethylene (with 5 % 10B) with 10 cm in thickness is sufficient to reduce effective dose less than 20 mSv/year.
