The purpose of this research was to propose pedagogical and didactic strategies for teaching radiation protection at higher education and university levels, with the aim of optimizing radiological safety in the Democratic Republic of Congo (DRC). This was done after evaluating the implementation of protective measures against the harmful effects of X-rays in conventional radiology in Kinshasa hospitals. To achieve this, we conducted a survey in 23 Kinshasa hospitals with a sample of 400 health professionals, including 100 radiologists, to assess the level of implementation of radiation protection principles in order to propose pedagogical and didactic remediation in initial training where necessary. In addition to interviewing the respondents, we collected radiophysical parameters to evaluate the degree of irradiation in pediatric and adult radiology services in Kinshasa hospitals. After analyzing the data, the following results were recorded: the surveyed health personnel reported that more than 40% of requested radiology examinations are not justified. Eleven services were found to be highly irradiating in pediatrics (48%) and two radiology services in adults (9%). Finally, all surveyed radiologist health personnel in Kinshasa do not know how to evaluate the degree of irradiation in their services. In light of these results, we proposed pedagogical and didactic remediation in radiation protection teaching during initial training to enable future health professionals to demonstrate competencies for optimizing radiological safety.
The global concern surrounding the advancement of methods for treating wastewater and polluted soil has markedly increased over time.While electrochemical advanced oxidation processes(EAOPs)and biotreatments are commonly employed technologies for remediating wastewater and polluted soil,their widespread adoption is hindered by their limitations,which include high costs associated with EAOPs and prolonged remediation time of biotreatments.In the review,we provided an overviewof EAOP technology and biotreatment,emphasizing the critical aspects involved in building a combined system.This review systematically evaluates recent research that combines EAOPswith bioremediation for treating wastewater or contaminated soil as pretreatment or post-treatment process.Research findings suggest that the combined treatment method represents a promising and competitive technology that can overcome some of the limitations of individual treatments.Additionally,we discussed the potential applications of this technology in varying levels of wastewater and soil pollution,as well as the underlying combination mechanisms.
