Dakriyo Sintigrafisi Yapılan Hastaların Çevreye Yaydığı Radyasyon Doz Düzeyinin Belirlenmesi

Bu çalışmada dakriyosintigrafi görüntüleme yapılan hastaların çevreye yaydığı radyasyon doz rate leri belirlenmiştir. bunun için radyofarmasötik enjeksiyonundan sonra 8,23, 41,68. ve 56,81. dakikalarda radyasyon doz hızı ölçülmüştür. Ayrıca hastanın ön tarafından 12 nokta belirlenmiştir. Bu noktalar kafa hizasından 25, 50, 100 ve 200 cm uzaklıkta, göğüs hizasından 25, 50, 100, ve 200 cm uzaklıkta ve ayak hizasından 25, 50,100 ve 200 cm uzaklıktadır. Bu noktalardan 3 farklı zaman olmak üzere bir hastadan 36 farklı ölçüm yapılmıştır. ölçümler sonucu ortalama doz hızı zaman ve ölçüm noktasına göre değişmekte olup 0,22 µSh-1 ile 2,86 µSh-1 arasında bulunmuştur.

Determination of the Radiation Dose Level Emitted to the Environment in Patients Undergoing Dacryo Scintigraphy

In this study, the radiation dose rates emitted by patients who underwent dacryoscintigraphy imaging were determined. For this, the radiation dose rate was measured at the 8.23, 41.68 and 56.81 minutes after the injection of the radiopharmaceutical. In addition, 12 points were determined from the front of the patient. these points are 25, 50, 100 and 200 cm from the head level, 25, 50, 100, and 200 cm from the chest level and 25, 50, 100 and 200 cm from the foot level. 36 different measurements were made from one patient, at 3 different times, from these points. As a result of the measurements, the average dose rate varies according to time and measurement point and was found between 0.22 µSh-1 and 2.86 µSh-1.
