Radioiodine-131 is commonly used for treatment of hyperthyroidism but there are few available data on the effects this male gonadal function. The untoward (131)I have been mainly studied in patients treated with high doses thyroid cancer. In present work we absorbed radiation dose to testes and testicular function hyperthyroid men after treatment.Nineteen were enrolled study before therapy. Seventeen had Graves' disease two toxic adenoma. was subdivided into parts: a dosimetric clinical...
Nine laboratories participated in an intercomparison exercise organised by the European Radiation Dosimetry Group (EURADOS) for emergency radiobioassay involving four high-risk radionuclides (239Pu, 241Am, 90Sr and 226Ra). Diverse methods of analysis were used participating vitro determination each urine samples. Almost all are sensitive enough to meet requirements derived this project reference Clinical Decision Guide introduced NCRP. Results from most ISO 28218 on accuracy terms relative...
The Global Health Security Initiative (GHSI) established a laboratory network within the GHSI community to develop collective surge capacity for radionuclide bioassay in response radiological or nuclear emergency as means of enhancing capability, health outcomes and resilience. partners conducted an exercise collaboration with WHO Radiation Emergency Medical Preparedness Assistance Network IAEA Response Network, test participating laboratories (18) their capabilities vitro assay biological...
Whole-body counters (WBCs) are used for the assessment of internal contamination actinides in human body. WBCs require adequate calibration procedures that rely on use suitable phantoms. A previous study carried out at ENEA-Radiation Protection Institute was aimed designing a head phantom which heterogeneous distribution 241Am point sources could satisfactorily approximate an assumed homogeneous throughout bones. Suitable correction factors WBC detection efficiencies were evaluated with...
The CONRAD Project is a Coordinated Network for Radiation Dosimetry funded by the European Commission 6th Framework Programme. activities developed within Work Package 5 ('Coordination of Research on Internal Dosimetry') have contributed to improve harmonisation and reliability in assessment internal doses. tasks carried out included study uncertainties refinement IDEAS Guidelines associated with evaluation doses after intakes radionuclides. implementation quality assurance new biokinetic...
The Global Health Security Initiative (GHSI) established a laboratory network within the GHSI community to develop their collective surge capacity for radionuclide bioassay in response radiological or nuclear emergency. A recent exercise was conducted test participating laboratories capabilities screening and vitro assay of biological samples, performing internal dose assessment providing advice on medical intervention, if necessary, using urine sample spiked with single radionuclide, 241Am....
The present study deals with the 24-h changes in circulating lymphocyte subpopulations eight subjects kidney grafts established for 2 to 5 years and treated cydosporin. control group consisted of ten age-matched clinically healthy subjects. chronobiological analysis time series documented that circadian rhythm T-lymphocyte subsets is undetectable transplanted Cortisol rhythmicity persists, however, suggesting abolition T-cell not attributable a desynchronisation adrenal cycle. Even though...
In order to properly respond an emergency caused by accident in a nuclear power plant with spread of radionuclides the atmosphere, we propose field procedure perform large-scale individual thyroid monitoring internal contamination due inhalation 131I, means non-spectrometric equipment, particular dose rate meters. Specific attention is paid children, because very high radiosensitivity child's carcinogenic effects ionising radiation. The device performance was evaluated measuring mock iodine...
The results obtained in a measurement campaign concerning internal contamination by the gamma-emitting radionuclides of large number individuals are presented this work. aim is to assess effectiveness spectrometric method an emergency response following nuclear power plant accident or spread atmosphere due act terrorism. An HPGe portable spectrometer, deployed collective protection apparatus, was used for both whole-body and thyroid measurements. adult bottle mannequin absorption (BOMAB)...
This study deals with a chronobiological approach to the circadian rhythm of renin-angiotensin-aldosterone system (RAAS) and ACTH-cortisol axis (ACA) in patients Addison's disease (PAD). The aim is explore mechanism(s) for which rhythmicity RAAS ACA takes place. has shown that both are devoid PAD. lack renin ACTH provides indirect evidence their rhythmic secretion some way related oscillation aldosterone cortisol. implies new concept: positive feedback may be included among mechanisms...
