Abstract:

During the comprehensive maintenance of nuclear power plants, the purification of the reactor pool is a critical task. Integrating foam decontamination with traditional high-pressure water washing can effectively shorten decontamination time and reduce radiation exposure to maintenance personnel. This study developed a novel foam decontamination agent through experimentation, assessing the effects of each component in the decontaminant on the foaming and liquid-carrying capabilities of the foam solution. Immersion corrosion tests confirmed that this foam decontaminant does not corrode the reac

Abstract:

Treatment of peri-implantitis through several implant surface decontamination techniques have been reported, however, some of them can negatively alter the implant surface or enhance more bacterial resistance. The aim of this in vitro study was to evaluate implant surface decontamination by means of Er,Cr:YSGG and diode lasers. Fifty micro-textured (MTX) dental implants were contaminated with Acinetobacter baumannii (n = 25) and with Pseudomonas aeruginosa (n = 25). All implants were then divided into five groups for the decontamination procedure. In group I (GI), decontamination was done with

Decontaminating N95 respirators for reuse could mitigate shortages during the COVID-19 pandemic. Although the United States Center for Disease Control has identified Ultraviolet-C irradiation as one of the most promising methods for N95 decontamination, very few studies have evaluated the efficacy of Ultraviolet-C for SARS-CoV-2 inactivation. In addition, most decontamination studies are performed using mask coupons that do not recapitulate the complexity of whole masks. We sought to directly evaluate the efficacy of Ultraviolet-C mediated inactivation of SARS-CoV-2 on N95 respirators. To that

The microbiological safety of food has been a major concern in Bangladesh following several reports of food borne outbreaks associated with contaminated food and vegetables. To minimize the outbreak, several studies suggested that decontamination is necessary before cooking. Washing with water is the most common technique for decontamination in Bangladesh. In order to ensure food safety, the use of different food washing agents is also becoming popular day by day. For this reason, this study was conducted to evaluate the efficacy of various sanitizers and treatment method for decontamination.

This paper describes innovative and inexpensive formulations that can be employed as ‘eco-friendly’ tools for the safe decontamination of radiopharmaceuticals spills or other accidental radioactive contamination of the surfaces arising from general-purpose radioisotope handling facilities (radiopharmaceutical laboratories, hospitals, research laboratorie

Abstract:

An important amount of cytotoxic drug may accumulate in the workplace following the breakage of a vial containing an anticancer drug. Thanks to the monthly monitoring of the surface contamination in our compounding unit, a strong increase of cyclophosphamide contamination was highlighted in the storage area following the breakage of the vial, despite application of the emergency procedure. This study presents an analysis of chemical decontamination in the context of massive contamination. Samples were taken on the floor and on the caster of a storage shelf where the vial broke.

Abstract:

To investigate the microbiological effects of a hide-on carcass decontaminating treatment recently implemented at a beef packing plant, carcasses undergoing routine processing at the plant were sampled during successive periods in January/February, April/May, and September/October. During each period, samples were collected from carcasses before and after the decontamination of hide-on carcasses, after skinning, before decontamination of the skinned carcasses, and at the end of the carcass dressing process. At each stage of processing during each period, samples were obtained by swabbing an ar

ABSTRACTMolten salt flameless oxidation of graphite is one of the prospective methods of irradiated graphite waste processing. Molten salts are capable to retain a considerable part of radionuclides, to neutralize acidic off gases, moreover spent salts could be vitrified on completion of the process. We have used thermodynamic modelling to assess the efficiency of molten salt oxidation of graphite. Equilibrium compositions of both the melt and the off gas were calculated depending on graphite content and temperature. The feasibility of decontaminating the irradiated graphite of its near-surfac

Abstract:

According to the characteristics of methanol leakage hazard, a new kind of foam decontamination agent was prepared and tested. Experiments were conducted in a laboratory-scale apparatus, where the effect of composition and amount on the decontamination performance of the foam was studied in detail. Results showed that the decontaminating efficiency of the foam was above 92% with the volume of foam agent sprayed 3 times of the methanol leaked. Moreover, the thick foam layer could stably cover the liquid methanol for a long time, efficiently inhibiting the volatilization of methanol vapor. Such

The article provides a detailed review of recent studies examining the role of probiotics in the degradation of aflatoxins, highly toxic compounds in food that pose significant health risks. Regulatory standards for aflatoxin levels in foodstuffs have been established to protect public health. Various methods—chemical, physical, and biological—have been developed for decontaminating and detoxifying aflatoxins. Among biological methods, probiotics have shown substantial potential in decontaminating aflatoxins. Studies indicate that probiotics can reduce the bioavailability of a

Numerous microbes found in household toothbrushes can lead to contamination of the oral cavity. These microorganisms can survive on the toothbrush for several days or weeks. Several studies have found a link between tooth decay and toothbrush bacterial residues. As a result, toothbrush disinfection is critical for toothbrush and oral hygiene maintenance. Furthermore, brush disinfection is required to prevent disease transmission, especially in children, the elderly, and high-risk patients, such as those with immunodeficiency or undergoing organ transplants or chemotherapy.

AbstractDecontaminating patients who have been exposed to hazardous chemicals can directly benefit the patients’ health by saving lives and reducing the severity of toxicity. While the importance of decontaminating patients to prevent the spread of contamination has long been recognized, its role in improving patient health outcomes has not been as widely appreciated. Acute chemical toxicity may manifest rapidly—often minutes to hours after exposure. Patient decontamination and emergency medical treatment must be initiated as early as possible to terminate further exposure and treat the effect

The main problem in processing bovine colostrum is preserving as many beneficial compounds as possible, most of which have low thermal stability. The present study evaluates the possibility of using cold plasma (CP) as a decontamination technology and its effect on selected biologically active fractions of freeze-dried bovine colostrum. The plasma process was carried out in air, nitrogen, and oxygen environments. The results revealed that the sterilization process using CP caused slight changes in the colour of the samples expressed by the attributes ΔC, ΔL, Δh and ΔE. The decontamination effe
