An exploratory study of compliance with patient radiation safety standards amongst radiographers in Eswatini public hospitals
Authors:   , Shungube Amelia
Published: October 2024

The consequence of non-compliance with patient radiation safety standards is increased unnecessary radiation exposure with high chances of harmful biological effects. Somatic effects may take up to 40 years to manifest, which may cause radiographers to be careless with radiation protection compliance when used. Radiographers performing these procedures are trained to use the minimum amount of radiation necessary by observing the radiation safety standards. The study aimed to explore compliance with patient radiation safety standards by radiographers in Eswatini public hospitals in order to recommend appropriate compliance standards to the Eswatini Ministry of Health. Methodology The research questions were derived using a qualitative exploratory descriptive design, and constructivism paradigms. The data collection process consisted of in-depth one-on one interviews. The sample was selected based on a purposive sampling approach. This study was conducted in the public hospitals in four regions of Eswatini. Study participants were radiographers employed in public hospitals with working experience of at least two years. Data saturation was achieved with 13 participants. After the data were collected, they were transcribed verbatim and analyzed using thematic analysis. Findings Three themes emerged from the data analysis, namely: a) Participants' attitudes towards compliance with radiation safety standards; b) radiographers’ subjective norms; and c) perceived behavioral control factors. This study has revealed a gap in compliance with patients' radiation safety standards amongst radiographers employed in Eswatini public hospitals. Conclusion The study demonstrated awareness and knowledge of patient radiation safety standards amongst radiographers in Eswatini public hospitals. However, compliance with the standards remained a personal decision because radiographers are not obliged to comply. Moreover, other factors contributing to non-compliance included defective lead protective devices; unavailability of all the lead protective designs; inappropriate design of the department building; and unauthorized staff making unjustified x-ray requests. The establishment of a self-regulatory body may assist in improving the situation through the introduction of radiation safety officers who will establish national Radiography policies and guidelines and ensure that radiographers follow them.

Pectin is a natural heteropolysaccharide contained in plant cell walls and plant waste. In recent years, various alternative methods (enzymatic, microwave, ultrasonic) have been used to increase the yield of pectin, which can increase the efficiency of the process, pectin yield and improve quality. The principal advantages of using microwaves for the extraction of pectin from plant waste materials are the significant reduction in processing time, the higher yield of the natural polymer and the quality maintenance due to the more gentle processing conditions. The purpose of the work is to improve the method of pectin extraction from beet pulp using microwave treatment. Experiments were carried out to establish the optimal conditions of polysaccharide extraction. The pectin extraction was optimized by varying the microwave power, the pH of the medium, the processing time, the type of extracting agent (citric, malic, hydrochloric and acetic acids) and the ratio of beet pulp to extracting agent. A titrimetric method was used to determine the degree of esterification and the uronide component. Results and discussion. Extraction of pectin from sugar beet pulp includes the following main steps: polymer extraction by microwave treatment, pectin purification and drying. Among the studied parameters, the ratio of beet pulp to extracting agent and microwave processing time had a significant effect on the yield and properties of pectin. The highest yield of pectin (5.7%) was achieved at a heating power of 520 W, pH - 2.0, processing time of 30 minutes, using citric acid as the extraction agent and a beet pulp to extraction agent mass ratio of 15:1. IR spectra of the extracted pectin show the presence of characteristic bands typical of the pectin spectrum. Conclusions. Varying the parameters of pectin extraction from sugar beet pulp using microwave treatment allowed to increase the yield of pectin with desired characteristics. The perspective of using ecologically pure organic acids (citric and malic acids) as an extracting agent is shown.

Isonicotinic acid derivatives are used in the development of new antibacterial agents, active ingredients in pesticides and herbicides. In addition, isonicotinic acid is a precursor for the synthesis of isoniazid, one of the most effective anti-TB drugs. Considering the importance of isoniazid in the treatment of tuberculosis, improving methods of synthesizing isonicotinic acid has a direct impact on the availability and cost of this life-saving drug. The goal of this work was to investigate the efficiency of V-Cr-O catalyst in the oxidation of 4-methylpyridine to produce isonicotinic acid, to study its composition and properties. Research methods. Methods of chemical analysis, scanning electron microscope (SEM), Raman spectroscopy were applied. Results and Discussion. In this work, the processes of isonicotinic acid synthesis by oxidation of 4-methylpyridine on the V-Cr-O catalyst were studied. Analysis of the obtained results showed that with an increase in the water feed, there is a general tendency towards a decrease in the conversion of 4-methylpyridine at all temperatures. For example, at a temperature 300oC, the degree of conversion drops from 91.72% at 1.79 g/h to 84.20% at 6.6 g/h. The yield of isonicotinic acid increases as the amount of water rises, reaching its peak at 47.46% with a temperature of 360°C and a water supply of 6.6 g/h. In contrast, the minimum yield is only 15.27% at 280°C with a water supply of 1.79 g/h. This highlights the positive correlation between water supply and yield, especially at higher temperatures.

The weathering crust ore of the Kundybay deposit is a hard-enriched ore that contains such minerals as cherchite, bastnesite, kaolinite, etc., which are embedded in the matrix structure of other silicate rocks. These minerals contain rare earth (RE) and rare earth elements (REE). The multi-component structure and dense packing of minerals in the aluminosilicate matrix of the ore make it difficult to be blocking out. Determination of the optimal ore blocking method in order to extract RE and REE is an urgent task for today. The purpose of this work is to develop an effective method of leaching RE, REE and "white soot" from the weathering crust ores of the Kundybay deposit. Methods. Processing with soluble ammonium, magnesium and aluminium salts will allow estimation of the state of RE and REE in the ore. The indicator of RE and REE blocking out during leaching with sodium hydroxide is the transfer of silica into solution, due to which RE and REE form their own hydroxides, which can be subsequently transferred into solution by acid treatment. Acid leaching with sodium pyrosulfite, hydrofluoric acid and sulfuric acid will allow the RE and REE to be immediately transferred into solution. Results and Discussion. The main characteristics of the Kundybay deposit weathering crust ore were determined, such as: silica content, moisture content, base metals, RE and REE. Conclusion. The degree of extraction of RE and REE by soluble salts of ammonium, magnesium and aluminium did not exceed 2%, which indicates the existence of RE and REE in the form of their own minerals. Leaching with sodium hydroxide showed low recovery of silica, with RE and REE remaining in a difficult-torecover form. Leaching with a mixture of sodium pyrosulfite, hydrofluoric and sulfuric acids is a promising method for RE and REE recovery due to the complex effect of the components of this mixture.
