This is a pre-copyedited, author-produced version of an article accepted for publication in Radiation Protection Dosimetry following peer review. The version of record Kamiya T., Iimori T., Maeda Y., et al. Administered dosage and effective dose estimated from ⁸¹Rb-rubidium hydroxide for lung ventilation scintigraphy using ⁸¹ᵐKr noble gas.

The aim of this study was to estimate the administered dosage of ⁸¹ᵐKr noble gas as calculated by the radioactivity of ⁸¹Rb-rubidium hydroxide (⁸¹RbOH). The administered dosage was regarded as the total amount of ⁸¹ᵐKr noble gas. The radioactivity of ⁸¹ᵐKr was calculated using the radioactivity of ⁸¹RbOH at the examination, the beginning of inhalation, the inhalation duration and the attenuation volume from the generator to the patient for ⁸¹ᵐKr noble gas. In addition, we created an Internet survey and asked National University Hospital in Japan to respond to questions regarding the parameters of concern. Survey responses were provided by 38 hospitals (response rate was 90.5%). Twenty-seven hospitals (64.3%) examined lung ventilation scintigraphy using ⁸¹ᵐKr noble gas. The mean administered dosage and the effective dose of lung ventilation scintigraphy using ⁸¹ᵐKr noble gas were 35.8 ± 22.1 GBq and 0.97 ± 0.60 mSv, respectively.
