“…This work confirmed that patients who underwent PA chest x-ray examination receive higher radiation dose compared to other international published work by Kia et al,(1998), Serro et al,(1992) and NRPB (1996) but almost close to that obtained by Tung et al,(2001). The reason behind the higher doses may be attributed to differences in technical parameters used.…”

“…A recent national publication [1] , resulting from the Portuguese participation in the European project Dose Datamed II, sought to address the lack of research in this area, and found an average annual effective dose in Portugal of about 1 mSv/caput. This value was twice the value obtained in another national study in 1992 [2] . According to the latest study, and to the classification proposed by the European Commission [3] , Portugal was categorized as belonging to the countries with mean exposure, with CT scans being responsible for 74 % of the collective effective radiation dose [1] .…”

191 Biomedical and Biopharmaceutical Research J o r n a l d e I n v e s t i g a ç ã o B i o m é d i c a e B i o f a r m a c ê u t i c a Complementary diagnostic activities in Portugal: Computed Tomography AbstractThe use of Computed Tomography (CT) as a complementary diagnostic technique has increased internationally, most markedly in recent years. Despite the low frequency of CT scans compared to other radiology examinations, CT is characterized as contributing significantly to the effective (radiation) dose. In Portugal, it is estimated that CT contributed 74 % of the total collective effective dose. This review gathers data on the temporal evolution of the number of CT scans in Portugal, framed in an international context, based on national and international literature sources. It was concluded that, in Portugal, as internationally, the number of CT scans increased by approximately 10 % annually, between 1995 and 2011. Keywords: CT, complementary diagnostics, statistics, effective dose, PortugalResumo O recurso à Tomografia Computorizada (TC) como meio complementar de diagnóstico tem vindo a aumentar no panorama internacional, de forma mais acentuada nos últimos anos. Apesar da reduzida preponderância dos exames de TC face aos outros exames de radiodiagnóstico, a TC caracteriza-se por contribuir grandemente para a dose efetiva. Estima-se que em Portugal a TC contribuí para 74 % da dose efetiva coletiva total. Esta revisão reúne dados sobre a evolução temporal do número de exames de TC em Portugal, enquadrada no contexto internacional, com base em fontes de literatura nacional e internacional. À semelhança da realidade internacional, concluiu-se que, em Portugal, o número de exames aumentou aproximadamente 10 % anualmente, entre 1995 e 2011.Palavras-chave: Tomografia Computorizada, meios complementares de diagnóstico, estatística, dose efetiva, Portugal

Diagnostic X-ray is one of the ionizing radiation that plays an important role in medical examination. Despite its great benefit, it is considered the largest source of artificial radiation exposure to public. The aim of the study is to measure the entrance surface dose (ESD) of patients undergoing chest, lumber spine and knee Xray examination using TLD-100. The mean Entrance surface dose of chest (PA), lumber spine (AP, LAT) and knee (AP, LAT) are 1.3mGy, 8.57mGy, 21.5mGy and 0.49mGy, 0.48mGy respectively. The ESDs measured were found to be higher than the published work.
