Evaluation of internal exposure of nuclear medicine staff working with radioiodine in Poland.

The iodine-131 (I-131) content in the thyroid of staff members working with this radionuclides has been measured with about 500 employees in about 25 hospital's departments of nuclear medicine performing therapy and diagnosis of thyroid disease in Poland. The measurements were performed with portable detection unit for measurements of radioiodine. This is consist with scintillation detector sodium iodine activated by thallium (NaI(Tl)) - battery-powered and portable tube base Multichannel Analyzer Canberra UniSPEC.

Retrospective Biological Dosimetry at Low and High Doses of Radiation and Radioiodine Impact on Individual Susceptibility to Ionizing Radiation.

Iodine-131 (I-131) is often used in thyroid diagnostics and therapy. External and internal exposure to radioiodine can lead to molecular and cellular damage in peripheral blood lymphocytes. The aim of this study was to explore the influence of low and high doses of I-131 on susceptibility to ionizing radiation.

Assessment of exposure of workers to ionizing radiation from radioiodine and technetium in nuclear medicine departmental facilities.

Background: Due to its use of ionising radiation, the field of nuclear medicine is a unique and significant part of medical diagnostics and patient treatment. The aim of this study was to assess the internal exposure of nuclear medicine employees to radioiodine 131I and technetium 99mTc as well as to assess the external exposure doses.

Material And Methods: The radioiodine 131I and technetium 99mTc contents in the thyroid of staff members (about 100 persons) dealing with these radionuclides have been measured in four departments of nuclear medicine.

Abnormal nerve conduction velocity as a marker of immaturity in childhood muscle spinal atrophy.

Motor conduction velocity (CV) was tested in 117 infants and children with proximal spinal muscular atrophy (SMA), aged 1-53 months, and in 99 age-adjusted healthy controls. The children were classified into SMA forms 1 and 2 according to SMA International Consortium Criteria. In all children CV was tested in four nerves and the following parameters were taken into account: distal latency, conduction velocity, amplitude of muscle response.
