The purpose of this study was to assess the effective dose received by children during cardiac procedures. 6 children from 3 to 14 years old who underwent coronary angiogram, cardiac catheterization and pulmonary valvuloplasty treatment were included in the present study. Measurement of effective doses of the paediatric cardiac patients was performed in four catheterization laboratories in three hospitals. Harshaw TLD badges (TLD-100, LiF: Mg, Ti) were used on patients to measure effective dose in the catheterization laboratory. The TLD badges were calibrated from Secondary Standard Dosimetery Laboratory. It is found that the highest dose was 2.01 mSv in 5.4 minute fluoroscopic time during peripheral angiogram and primary pace maker procedure and the lowest effective dose was 0.044 mSv in 1.2 minute fluoroscopic time during coronary angiography performed in the same hospital. The highest fluoroscopic time (18:14 min) was taken to perform a cardiac catheterization and pulmonary valvuloplasty procedure and the dose was 0.781 mSv. During cardiac catheterization children were exposed to high levels of radiation but there was a variant in dosage. Careful consideration should be given to minimize dosage by practicing ALARA principle. This type of study may lead cardiologist and scientist to improve necessary safety measures to be taken to reduce the exposure to patients and occupational worker.

Abstract The present study evaluated the organ doses, effective doses and conversion factors from the dose–area product to effective dose in pediatric diagnostic cardiac catheterization performed by in-phantom dosimetry and Monte Carlo simulation. The organ and effective doses in 5-y-olds during diagnostic cardiac catheterizations were evaluated using radiophotoluminescence glass dosemeters implanted into a pediatric anthropomorphic phantom and PCXMC software. The mean effective dose was 3.8 mSv (range: 1.8–7.5 mSv). The conversion factors from the dose–area product to effective dose were 0.9 and 1.6 mSv (Gy cm2)−1 for posteroanterior and lateral fluoroscopy, respectively, and 0.9 and 1.5 mSv (Gy cm2)−1 for posteroanterior and lateral cineangiography, respectively. Effective doses evaluated using the pediatric dosimetry system agreed with those obtained using PCXMC software within 12%. The dose data and conversion factors evaluated may guide the estimation of exposure doses in children undergoing diagnostic cardiac catheterization.

Occupational Radiation

There has been an increase in the numbers of diagnostic and therapeutic procedures, which, in turn, has increased the occupational radiation doses delivered to healthcare practitioners. The aim of this study is to estimate a baseline for the occupational effective doses for five consecutive years (2016–2020) among nurses working in several medical departments in Saudi Arabia. A total of 3249 nurses were monitored from 2016 to 2020. Occupational effective doses were estimated using thermoluminescent dosimeters (TLD-100 chip) made of lithium fluoride (Li natural) LiF:Mg.Ti materials. An analysis of the dosimetry data revealed that the overall mean annual effective dose (MAED), range of the effective doses and the mean collective effective dose for nurses in selected departments during the study period were 0.85 mSv, 0.06–13.07 mSv and 46.51 man-mSv, respectively. The MAEDs for nurses were obtained from various departments, including the operating room (OR; 0.81 mSv), general X-ray (0.90 mSv), cardiac catheterization laboratory (cath-lab; 0.97 mSv), endoscopy (0.79 mSv), computed tomography (CT; 0.77 mSv), fluoroscopy (0.81 mSv), dentistry (0.92 mSv), angiography (0.91 mSv), nuclear medicine (1.01 mSv), urology (0.68 mSv), radiotherapy (0.67 mSv) and mammography (0.77 mSv). The MAED for cath-lab nurses was significantly higher than that for OR, CT and endoscopy nurses. The occupational doses among nurses in Saudi Arabia were below the recommended dose limit of 20 mSv. However, to further reduce the occupational dose, we recommend training and continuing education in radiation protection for nurses involved in radiological procedures.

Average Effective Dose

Interventional cardiac procedures result in substantial patient radiation dose due to prolonged fluoroscopy time and radiographic exposure. Patient dose measurement is performed in two catheterization laboratories in Square Hospital Ltd, Dhaka. A total of 50 patients of Square Hospital is included in this study. TLDs are used for the measurement of the dose received by patients during interventional cardiology at Square Hospital, Dhaka. Patients, who underwent CAG, PTCA, and (CAG with PTCA) have average effective dose 3.30 mSv with a range from 0.96 to 9.12 mSv, 24.14 mSv with a range from 7.56 mSv to 56.81 mSv and 25.56 mSv with a range from 1.21 mSv to 95 mSv respectively. Our results correspond well with those obtained by authors in other countries of the world. This study would be useful to establish a database of the patient’s dose for CAG and PTCA. This may lead cardiologists and scientists to adopt necessary safety measures for reducing exposure to patients and occupational workers.J. Asiat. Soc. Bangladesh, Sci. 40(1): 1-7, June 2014

Abstract It is inevitable that we are exposed to radiation daily from various sources and products that we consume on daily basis. The use of toothpaste for oral hygiene is one of the most common daily practices by humans and yet very little data are available regarding its radiation content. In this work, we investigated the concentrations of gamma emitting radionuclides in toothpaste samples consumed in Jordan. 40K and 226Ra were detected in almost one-third of the samples, whereas 228Ra was detected in nearly half of them. The corresponding activity concentrations in the detected samples were in the ranges of 68.7–154.2, 4.6–14.1 and 1.3–10.0 Bq/kg, respectively. Dose assessment of accidental ingestion of toothpaste for children and adults was made, and its contribution to the annual effective dose was found to be very minimal with maximum doses of ~2.9 and 1.3 μSv for children and adults, respectively.
