Background: The aim of the study was to analyze the effective dose record of occupationally exposed radiation workers at Bahawalpur Institute of Nuclear Medicine and Oncology department. Materials and Methods: Annual effective doses of occupationally exposed workers were measured by film badge dosimetry by sending the dosimeters to Radiation Dosimetry Laboratory (RDL), Pakistan Institute of Nuc...

introduction: ionizing radiation induces various kinds of dna damage in which may lead to chromosomal aberrations (ca). inspite of growing importance in the risk assessment, the dose yield kinetics of ca and their implications for dose assessment are not well established in exposures to low level radiation. in the present study, cytochalasin-b blocked micronucleus assay and metaphase analysis w...

introduction: occupational exposure to ionizing radiation due to medical activities (both diagnostic and therapeutic procedures) has increased sharply in recent years. among the occupationally exposed workers in these fields, those most affected by this increased exposure to ionizing radiation are nuclear medicine workers. in this study, annual average effective dose, annual collective effectiv...

Introduction DNA damage is among the main consequences of radiation. Of many different classes of DNA damage, double-strand breaks are the most deleterious. Development of a sensitive biodosimetry method, which utilizes a detection material with a similar construction to the body, seems essential for monitoring radiation workers. In this study, histone H2AX protein was examined as a potential  ...

Background and Objective: Professional radiation workers are occupationally exposed to long-term low levels of ionizing radiation. Occupational health hazards from radiation exposure, in a large occupational segment of the population, are of special concern. Biological dosimetry can be performed in addition to physical dosimetry with the aim of individual dose assessment and biological effects....

introduction: a comparision of cytogenetic methods in the evaluation of occupationally received radiation dose by medical radiation workwrs and a study of adaptive response to subsequent higher radiation exposure in this group.the purpose of this research was to study the effects of two cryoprotectants on viability, motility, morphology and fertilization rate of mouse sperm after freezing-thawi...

BACKGROUND The workforce of the UK Atomic Energy Authority has been the subject of several previous epidemiological investigations. AIMS To detect and investigate associations between mortality rates and employment in a substantially increased cohort size and follow up extended to 1997. METHODS AND RESULTS The new cohort included 51 367 employees, of whom 10 249 were dead. Mortality rates f...
