In radiation synovectomy about 10 GBq 165Dy-ferric hydroxide is injected into major joints. Measurements of the dose rates were performed at distances of 5 cm, 0.5 m, 1 m and 2 m from the surface of the treated joints (knees) until 200 min after the application in 16 patients in order to estimate the radiation exposure of persons in the neighbourhood of the patients. The highest doses were estimated for the fingers of the technologist (320 µSv) and for the physician (700 µSv). Special shields for the syringes were constructed for dose reduction. The whole-body doses were 103 µSv for the technologist and 40 µSv for the physician. After the discharge of the patient to a ward or home, other persons at 1 m distance from the patient might receive 88 µSv, which is less than 9% of the annual permissible dose. Our results clearly demonstrate that the calculated radiation exposure to personnel and family members is well below the maximum annual dose limit for non-professionally exposed persons.
