Keywords: liquid waste, treatment, potassium cobalt ferrocyanide
Abstract: The present invention relates to the field of disposal of radioactive waste from nuclear plants, in particular to radioactive waste liquid. The method consists of heating the oil, of alkaline potassium permanganate, and ferrocyanide collector to 80oC, in volume ratio of the two being 0.5:5:0 (collector:oil), with formation of coagulant and subsequent separation of radioactive sludge. As ferrocyanide collector, 1. potassium cobalt ferrocyanide or 2. mixture of potassium nickel ferrocyanide and potassium cobalt ferrocyanide can be used.

Keywords: liquid waste, treatment, evaporation
Abstract: The invention relate to treatment of liquid radioactive wastes. The method consists of preliminary evaporation of the solution with obtainment of regenerated nitric acid and distillation residue. Then, neutralization of the distillation residue to pH1~2, and partial reduction of ferric iron, using sodium sulfite, to mixed valence state of Fe3+:Fe2+=2:1, are conducted.

Keywords: liquid waste, solidification
Abstract: Summary of invention: for solidification of liquid radioactive wastes, porous glass-ceramic blocks are applied, which is formed from hollow glass-ceramic microsphere, extracted from the fly ash from combustion of fossil fuels. The block operates as a sponge and is characterized by a high value of open porosity of uniform pore structure.

Title: Clinical Experiences with Radiation Induced Thyroid Cancer after Chernobyl

Keywords: Chernobyl; children; thyroid cancer; advanced stages; treatment; prognosis
Abstract:The risk of developing thyroid cancer increases considerably after exposure to external or internal radiation, especially in children below the age of 10. After the Chernobyl reactor accident, the yearly incidence of childhood thyroid cancer in Belarus increased to approximately 40 per 1.000.000 in girls and to roughly 20 per 1.000.000 in boys compared to approximately 0.5 cases per 1.000.000 prior to the accident. Typically, young children with thyroid cancer after radiation exposure present in ≈95% of the cases as papillary cancers, in ≈50% as invasive tumors growing outside the thyroid capsule, in ≈65% with lymph node metastases and in ≈15% with distant metastases. A joint Belarusian-German project starting in April 1993 that combined treatment with surgery and radioiodine was organized in 237 selected children from Belarus who were exposed to the Chernobyl fallout and had advanced stages of thyroid cancer. The study group included 141 girls and 96 boys. Their median age at the time of the accident was 1.7 years; whereas the median age at the time of diagnosis was 12.4 years. With the exception of two cases with follicular histology, the majority of the patients had been diagnosed with papillary thyroid cancers. In 63%, the tumor had grown outside the thyroid capsule and invaded the tissue of the neck (pT4). Nearly all of the selected cases (96%) showed-up with lymph node metastases (pN1) and 43% of the patients with distant metastases mainly to the lungs (pM1). In 58% of the children, complete remissions of thyroid cancer could be achieved until December 31st 2010 and in 34% of the children, stable partial remissions; in the remaining 8% of the patients, partial remissions were observed. The risk of radiation-induced thyroid cancer increased considerably in children and adolescents who were affected by the Chernobyl reactor accident. In spite of the fact, that thyroid cancers in young children seem to behave more aggressively than in older patients, the results of combined treatment with thyroidectomy, radioiodine therapy and thyroid hormone replacement are excellent.

Keywords: Chernobyl accident; Thyroid cancer; Incidence; Treatment; Thyroid radiation dose
Abstract: In the present paper are generalized data on the increase of thyroid cancer incidence in children and adolescents affected after the Chernobyl accident for the period 1986–2004. Beginning in 1990, a significant rise in the number of thyroid cancer cases and incidence was noted in the cohort aged 0–18 years at the time of the accident, especially among children aged 0–14 years. Patients’ distribution by age at the time of the accident points out that the most significant increase in the number of thyroid cancer patients occurred at the expense of children who were aged up to 4 years in 1986….
