Dose rates in the sample chamber of a 137Cs gamma-ray irradiation apparatus (Nordion International Inc., Gammacell 40 Exactor) were accurately measured using an ionization chamber dosimeter. The dose rates obtained were 5.2-7.2% higher at the upper and lower planes than at the middle plane in the sample chamber. In the process of starting and stopping the… CONTINUE READING
