| Popis: |
In the present paper an Alderson RANDO phantom have been used to experimentally determine conversion coefficients for external exposure. A limited number of exposure situations were investigated: rotational geometry with different radiation point sources (99mTc, 131I+133Ba, 137Cs, 60Co), APand PA-geometry with 137Cs and a special pocket-geometry with 137Cs. All experiments were carried out on a large open field to avoid scattering effects from walls and roof. The established conversion coefficients are a first step to later determine more conversion coefficients for more complex exposure situations. The coefficients presented here may therefore be used directly or as a comparison to Monte Carlo simulated values of the same exposure situations. |
