Abstract
ObjectiveTo inspect personal dose as an interventional radiologist for 40 years, to assess the enforcement number of interventional radiology (IR), and to check for radiation cataract.Materials and methodsI evaluated my own effective dose, an equivalent dose to the lens of the eye (EDL), and the number of IR procedures between March 2019 and June 1979. I examined the lens in June 2019 as a radiologist for 40 years.ResultsThe accumulation dose was 0 mSv in 1979–88. During 1989–93, the right crystalline lens equivalence of the value dose was measured. During 1993–96, two badge items for the head, neck, and abdomen were present. Both were distributed, but attaching to the same part and reversing occurred frequently. The EDL of the recent 5 years has exceeded 100 mSv. No association with the number of IR procedures was recognized. Posterior subcapsular vacuoles (PSV) as the early changes of the radiation cataract were recognized as four on the left and one on the right.ConclusionIt is important to get accustomed to film badge wearing, and the cancelation of making a mistake in the wearing part. Radiologists should check the PSV at a stage beyond a certain constant dose.
Highlights
Materials and methodsIn 2011, the International Commission on Radiation Pro‐ tection (ICRP) issued a recommendation on the equivalent dose limit for the lens of the eye for occupational exposure, which will be implemented in Japan from April 2021 [1, 2]
I decided to verify the substance of my personal individual dose management that I have been working as a radiologist for 40 years, the rela‐ tionship between equivalent dose to the lens of the eye and the number of interventional radiology procedures, and the presence or absence of radiation cataract
As the individual dose measurement was managed by uniform exposure, it was performed by the chest film badge, which was mounted at the chest pocket of the white robe
Summary
In 2011, the International Commission on Radiation Pro‐ tection (ICRP) issued a recommendation on the equivalent dose limit for the lens of the eye for occupational exposure, which will be implemented in Japan from April 2021 [1, 2]. Along with this recommendation, I decided to verify the substance of my personal individual dose management that I have been working as a radiologist for 40 years, the rela‐ tionship between equivalent dose to the lens of the eye and the number of interventional radiology procedures, and the presence or absence of radiation cataract. I took the lens examination in June 2019, when I was active as a radiologist for 40 years
