Introduction to Chemical Decontamination

Here we present a newly developed two-step oxidative-reductive in-service chemical decontamination process suitable for high temperature and high pressure circuit (HTHPC) decontamination in a pressurized water reactor (PWR).

0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited Chemical decontamination of primary systems in a nuclear power plant (NPP) prior to commencing the main decommissioning activities is required to reduce radiation exposure during its process.

Results: Respondents agree that the efficacy of mechanical and chemical decontamination of implant surfaces needs to be improved and better documented.

Electrolyzed water can replace conventional chemical decontamination methods in the industry and household.

These entail acetylcholinesterase reversible inhibitors, receptor modulators, as well as chemical and biochemical decontamination involving nerve agent degradation and elimination.

The principal sources of organic complexing agents in low level radioactive wastes (LLW) originate from chemical decontamination activities.

Chemical decontamination during processing is used in many countries to mitigate the Campylobacter load on chicken meat.

Methods: To examine the efficacy of chemical decontamination, we used high-density, semi-quantitative environmental sampling to detect SARS-CoV-2 on surfaces in a COVID-19 ICU and COVID-19 ICU antechamber.

Removal of passive/corrosion oxide film comprising radioactive nuclides from the alloy surfaces forms a decisive step during the chemical decontamination process development in the nuclear industry.

Among the latter, pulsed light may be an effective, non-chemical decontamination alternative.

So, it was concluded that O3+US treatment for 10 min can be employed for microbial and chemical decontamination in spinach leaves at household level without any negative effect on its quality up to 1 week under refrigerator storage (5 ± 2 ○C).

These data provide insight into the real-world use of ZH as a reactive sorbent for chemical decontamination applications.

Traditionally, strategies to counter the toxicity of such substances consist of chemical decontamination/physical removal of the residual agent from the skin surface (preferably as soon as possible following the exposure) and administration of antidotes in the case of intoxication signs.

All patients were treated with the same surgical approach: antibiotic therapy, mechanical curettage, chemical decontamination and xenograft application.

Background Hydrogen peroxide and ozone have been used as chemical decontamination agents for N95 masks during supply shortages.

Based on the results of the tests, a device for the electrochemical decontamination of metal surfaces of equipment in non-stationary conditions was created and design and technological documentation for its serial production was developed.

Various chemical decontamination methods (isopropyl alcohol (IPA), vaporized hydrogen peroxide (VHP) and detergent) have been explored in the present study.

Reuse approaches focused on reusing plastic tubes via a chemical decontamination station and autoclaving, facilitating the reduction of single-use plastics and a decrease in the amount of waste generated.

Insufficient root canal preparation may prevent effective chemical decontamination and obturation to the full working length.

Due to their persistence, polychlorinated biphenyls (PCBs) represent a group of important environmental pollutants, but conventional physicochemical decontamination techniques for their removal are usually expensive.

Thus, chemical decontamination technology is of great significance to the decommissioning of nuclear energy facilities.

BACKGROUND This quantitative, comparative-descriptive study of inpatient units in a large military medical center was designed to compare the effectiveness of compact ultraviolet (UV-C) decontamination to standard chemical decontamination in reducing the microbial burden on Vocera (San Jose, CA) communication devices and to characterize changes in staff cleaning practices following UV-C device implementation.

A UVC photo-Fenton advanced oxidation process (AOP) was studied to develop a process for the decomposition of oxalic acid waste generated in the chemical decontamination of nuclear power plants.

Surgical therapies combined with mechanical and chemical decontamination contributed to peri-implant tissue health.

Therefore the chemical decontamination of alkaline oxidizing and acid reducing steps had no negative effect on corrosion of 304L SS and reoxidation of 304L SS carried out decontamination.

Hospital facilities are often cleaned with marketed antimicrobials whose chemical decontamination efficacy certainly differs but remains unknown.

Recent data confirm that using a specific chemical decontamination solution is helpful in removing traces of contaminants.

This study developed the chemical decontamination process though the development project of decontamination technology of reactor coolant system and dismantled equipment for NPP decommissioning, which has been carried out since 2014.

An experimental setup is presented to assess the possibility of using the method of electrochemical decontamination of irradiated graphite.
