Here we describe the first clinical experiences regarding the use of an automated radiation dose management software to monitor the radiation dose of patients during routine examinations. Many software solutions for monitoring radiation dose have emerged in the last decade. The continuous progress in radiological techniques, new scan features, scanner generations and protocols are the primary c...

introduction radioactive materials naturally exist in the world. indeed, approximately 82% of human-absorbed radiation doses, which are out of human control, arise from natural sources of radiation including cosmic, terrestrial, and exposure through inhalation or ingestion. thus, the aim of the present study was to estimate health risk, as well as the effective and organ doses from naturally oc...

There is strong evidence that ionizing radiation increases cancer risks at high doses (e.g., >1 Gy), and persuasive, if controversial, epidemiological evidence that cancer risks are increased at low doses ( 10 mGy). Discussed here are the issues related to extrapolating radiation risks from low radiation doses to very low doses (<1 mGy) — for which purpose we are forced to rely on radiobiologic...

background: therapeutic radiopharmaceuticals are designed to deliver high doses of radiation to selected target organs with an aim of minimizing unwanted radiation to surrounding healthy tissue. due to the potential of targeted radiotherapy to treat a wide range of malignant conditions, [153sm]-samarium maltolate was developed for possible therapeutic applications. materials and methods: the or...

Aim: To determine the effects of single doses of b radiation on the wound healing functions of human Tenon’s capsule fibroblasts (hTf). Methods: hTf were grown in tissue culture and irradiated with b radiation using a strontium 90 source. The effects of b radiation on fibroblast migration was studied using microporous transwell membranes. The effects of radiation on fibroblast contraction was i...

Background: There is not any report on the radiation doses received by patients in diagnostic radiology sections in hospitals under control of Chaharmahal and Bakhtiari Medical Sciences University, in the south west of Iran. Objectives: The aim of this study is measurement of entrance surface doses (ESD) for the most routine types of X-ray procedures in radiology centers as part of ongoing d...

AIM To determine the effects of single doses of beta radiation on the wound healing functions of human Tenon's capsule fibroblasts (hTf). METHODS hTf were grown in tissue culture and irradiated with beta radiation using a strontium 90 source. The effects of beta radiation on fibroblast migration was studied using microporous transwell membranes. The effects of radiation on fibroblast contract...
