The technical passport for the X-ray room in accordance with the current sanitary legislation is a mandatory document certifying the technical condition of X-ray diagnostic equipment, devices for developing, fixing and drying X-ray films, additional equipment and accessories for performing special types of X-ray diagnostics, means of protection against ionizing radiation of workplaces of the office staff and adjacent to the office of the premises and confirming the compliance of their characteristics with the normative and technical documentation and domestic standards. The purpose of this work was to assess the relevance and necessity of issuing a technical passport for the X-ray room and to coordinate the project of the X-ray room with the X-ray department in the light of the current sanitary legislation. Registration of a technical passport by organizations that have special permits for these types of work, and not only by the X-ray and radiological department, would increase the legal value of the technical passport. The information contained in the technical passport is duplicated in the rest of the documentation for the X-ray room, the requirements for which are enshrined in the sanitary legislation, which generally casts doubt on the need for a technical passport as a mandatory document.

Alloy Surface Layer

The main aim of the study was the evaluation of magnesium alloy surface treatment effectiveness using high-energy heat sources, i.e. a Yb-YAG Disk Laser and the GTAW method. The AZ91 and AM60 commercial magnesium alloys were subject to surface layer modification. Because of the physicochemical properties of the materials studied in case of the GTAW method, it was necessary to provide the welding stand with additional equipment. A novel two-torch set with torches operating in tandem was developed within the experiment. The effectiveness of specimen remelting using a laser and the GTAW method was verified based on macro- and microscopic examinations as well as in X-ray phase analysis and hardness measurements. In addition, the remelting parameters were optimised. The proposed treatment methodology enabled the achieving of the intended result and effective modification of a magnesium alloy surface layer.

Medical Exposure

Objective: Physicians who often request for computed tomography (CT) scan examinations are expected to have sound knowledge of radiation exposure (risks) to patients in line with the basic radiation protection principles according to the International Commission on Radiological Protection (ICRP), the Protection of Persons Undergoing Medical Exposure or Treatment (POPUMET), and the Ionizing Radiation (Medical Exposure) Regulations (IR(ME)R). The aim is to assess the level of requesting physicians’ knowledge of ionizing radiation from CT scan examinations in two Nigerian tertiary hospitals. Materials and Methods: An 18-item-based questionnaire was distributed to 141 practicing medical doctors, excluding radiologists with work experience from 0 to >16 years in two major teaching hospitals in Nigeria with a return rate of 69%, using a voluntary sampling technique. Results: The results showed that 25% of the respondents identified CT thorax, abdomen, and pelvis examination as having the highest radiation risk, while 22% said that it was a conventional chest X-ray. Furthermore, 14% concluded that CT head had the highest risk while 9% gave their answer to be conventional abdominal X-ray. In addition, 17% inferred that magnetic resonance imaging had the highest radiation risk while 11% had no idea. Furthermore, 25.5% of the respondents have had training on ionizing radiation from CT scan examinations while 74.5% had no training. Majority (90%) of the respondents were not aware of the ICRP guidelines for requesting investigations with very little (<3%) or no knowledge (0%) on the POPUMET and the IR(ME)R respectively. Conclusion: There is low level of knowledge of ionizing radiation from CT scan examinations among requesting physicians in the study locations.

Intraoral periapical radiograph examination is the additional examination which is the most widely used in Dentistry. This radiograph examination using an x-ray ionizing radiation with low LET (Linear Energy Transfer), and may affect submandibular salivary gland. Ionizing radiation exposure can cause damage by inducing a series of changes at the molecular and cellular level. This study aimed to prove the effects of x-ray ionizing radiation with low LET towards the catalase activity of Rattus norvegicus strain Wistar’s submandibular gland. The subjects were 28 male Wistar rats and divided into 4 groups (n=7). Three groups were exposed 4, 8 and 14 times to radiation with 0.002 µSv for each exposure. The catalase activity of each rat was examined by a spectrophotometer. Data were analyzed using one-way ANOVA followed by Bonferroni test. The results showed the average of catalase activity on Wistar rat’s submandibular gland, respectively for: 0.150±0.0895 (KK), 0.1405±0.0607 (K1), 0.1228±0.0290 (K2), 0.1227±0.0556 (K3). Data showed significant differences of catalase activity between test groups, but showed not significant differences of catalase activity between each groups of Rattus norvegicus strain Wistar’s submandibular gland. In this study concluded decreased catalase activity of Rattus norvegicus strain Wistar’s submandibular gland resulting from x-rays ionizing radiation by 4 times, 8 times and 14 times exposures.

Renewal Project

The functionalist villa Tugendhat in Brno is a first monument of modern architecture in the Czech Republic. This monument was registered in 2001 to the list of World Cultural and Natural Heritage by UNESCO. Among the most experts this building is usually regarded as a greatest work of German architect and designer Ludwig Mies van der Rohe. The complete renewal of this monument was ini­tia­ted due to unsatisfactory technical condition and because of the higher operational requirements. In this work we deal with the technical analysis of the villa Tugendhat interior furnishing, or more precisely with the structural analysis of its furniture joints. The goal of this work is to highlight the original construction and material solutions of the furniture in connection with the creation of production-technical documentation for the renewal. Project scope includes the complete constructional drawing documentation of the 53 pieces of furniture, documents relating to the surface treatment of the furniture, as well as documentation of manufacturing and constructional details. Described part of the project was prepared a few years ago by the Department of furniture, design and habitation. Nowadays, the project documentation is completed. Protracted legal disputes concerning this state contract still postpone the beginning of reconstruction of this monument.
