Ambient dose during intraoral radiography with current techniques: part 3: effect of tube voltage.

CONCLUSION: Higher tube voltage results in higher remnant-beam transmission and more scattered radiation per workload. The relation is linear in the range between 60kV and 70 kV. Remnant-beam transmission at 70 kV is safely assessed at 7.5%. A conversion factor at 60 kV of 0.035 µSv/mAs at one meter for the scattered radiation dose can be proposed. Total ambient dose per exposure was higher at 60kV than at 70 kV.
