Our aim was to prepare a radioactive lacrimal passages probe, study its dose distribution in a phantom and suggest security indexes and therapeutic effective doses for brachytherapy. We prepared the radioactive probes by laying 125I particles into plastic tubes. We conducted temperature tests, pressure tests, soak tests and shock tests, to obtain security indexes. The dose distributions in phan...

Effectiveness of the 1989 environmental protection regulations in reducing concentrations and biological effects of tributyltin (an organotin) a marine antifoulant, in Victorian coastal water-bodies.

Groundwater contamination is a serious threat to water supply. Risk assessment of groundwater contamination is an effective way to protect the safety of groundwater resource. Groundwater is a complex and fuzzy system with many uncertainties, which is impacted by different geological and hydrological factors. In order to deal with the uncertainty in the risk assessment of groundwater contaminati...

IMPORTANCE Contamination of the skin and clothing of health care personnel during removal of personal protective equipment (PPE) contributes to dissemination of pathogens and places personnel at risk for infection. OBJECTIVES To determine the frequency and sites of contamination on the skin and clothing of personnel during PPE removal and to evaluate the effect of an intervention on the frequ...

Phytoremediation of radioactive waste is a process that uses plants to remove, transfer, or immobilize radionuclides from the contaminated soil, sediment, sludge, or water, and it is a useful method for treating large-scale low-level radionuclide contamination. However, there have not been established criteria which can be utilized to screen out suitable plant species that are capable of remedi...

Kori Unit 1, which was permanently shut down in 2017, is expected to be the first decommissioned commercial nuclear power plant (NPP) Korea. Operating NPPs designate radiation-controlled areas (RCAs) protect workers from radiological hazards and provide appropriate measures. Decommissioning RCAs (DRCAs) being should also designated by considering characteristics of workplaces exposure routes de...

Background Proper feeding practices during early childhood is fundamental for optimal child growth and development. However, scientific evidences on the determinants of dietary diversity are scanty. Particularly, the impact of fasting on children`s dietary diversity is not explored in Ethiopia. The aim of this study was to assess dietary diversity and associated factors among children aged 6-23...

Swipe assays are routinely performed in laboratories and other facilities that use or handle radioactive materials. These assays, often referred to as smear or wipe tests, are performed to comply with radioactive material license requirements, assure laboratory safety, and provide information that proper handling procedures are being followed. Typically, swipes are performed to monitor for the ...

Existing remote radioactive contamination depth estimation methods for buried radioactive wastes are either limited to less than 2 cm or are based on empirical models that require foreknowledge of the maximum penetrable depth of the contamination. These severely limits their usefulness in some real life subsurface contamination scenarios. Therefore, this work presents a novel remote depth estim...
