The article presents results of a long-term (1998–2021) radiological monitoring survey recreation base located in wooded area the zone radioactive contamination after accident at Chernobyl nuclear power plant. Local mechanical decontamination soil had been made on territory 1997. evaluation secondary decontaminated was performed by comparing dynamics situation treated plot and control, nondecon...

In September 1987 an accident occurred with a cesium chloride (CsCl) teletherapy source taken from a cancer therapy institute in Goiânia, Brazil. Misuse of the abandoned source caused widespread contamination of radioactive material (about 50 TBq of Cs) in the town of Goiânia. Decontamination of affected areas did lead to about 3,500 m of solid radioactive wastes, which were disposed in two nea...

Introduction: Various iodine isotopes are undergoing radioactive decay except Iodine-127 (I-127. Iodine I-131 is unsealed radioactive material used in nuclear medicine for both diagnostic and therapeutic procedures in Royal Hospital since 2006. In radiotoxic classification, I-131 is in group 2 element. I-131 is highly reactive element due to its volatilization nature. Currently...

UNLABELLED In accord with as-low-as-reasonably-achievable and good-manufacturing-practice concepts, the present study evaluated the efficiency of radioactivity decontamination of materials commonly used in laboratory surfaces and whether solvent spills on these materials affect the findings. METHODS Four materials were evaluated: stainless steel, a surface comprising one-third acrylic resin a...

Nasal decontamination may be indicated when the anterior nasal passages are contaminated with highly radioactive material or radioactive material with either irritating or toxic properties. Nasal irrigation (wash, rinse, douche, lavage) is an established technique used for other conditions and can be applied in these cases. This paper discusses the rationale and use of nasal irrigation and how ...

experiments, for aqueous Cr(VI) solutions having low buffering capacities, over the Cr(VI) concentration range of 5 – 40 mg/L. The results showed that the initial Cr(VI) concentration significantly affects the reduction capacity of scrap iron. Maximum reduction capacity of scrap iron was observed at the beginning of the column experiments; the lower the Cr(VI) concentration, the greater the exp...

The paper is a short review on the soil decontamination applying ex-situ techniques. Some sources and pathways of soil contamination are discussed. It was revealed that available techniques for soil decontamination can be divided in two parts, depending on where the action have place: in-situ or ex-situ. Also, depending on the nature of the process, these techniques can be biological, physical-...
