Item type:Publication, Measurement of the 226Ra, 232Th and 40K activities in corn in the Republic of North Macedonia and resulting annual radiation dose by ingestion(University of Banja Luka Faculty of Agriculture University City Bulevar vojvode Petra Bojovića 1A 78000 Banja Luka, Republic of Srpska, B&H, 2021-05-27); ; ; Considering the fact that there has been a significant population growth and this increases the need of food, various agricultural activities are increasingly being used, including the use of phosphate fertilizers that can directly affect agricultural crops. Therefore, it is necessary to know the level of present radionuclides, especially in corn, which is very often used for the needs of people and animals. The purpose of this study was focused on comparing the activity concentrations of 226Ra, 232Th, 40K in corn samples, and the calculated results were the basis for the assessment of the external hazard index (Hex), the internal hazard index (Hin), the radium equivalent activity (Raeq), and the annual gonadal dose equivalent (Dgon). The gamma spectrometry technique was used for measurement of the samples, i.e. an instrument - gamma spectrometer (Canbera Packard) with a high purity germanium detector. The obtained spectra from the measurement were analyzed by using the GENIE 2000 program. Based on the performed examinations, the activity concentrations in corn ranged from 0.42 to 0.77 Bq kg - 1 for 226Ra, from 0.06 to 0.87 Bq kg - 1 for 232Th, and from 117.54 to 322.11 Bq kg - 1 for 40K. The mean value of the radiation hazard index, the Heks value is lower than the maximum allowed value which is <1 for Heks. The value of the radium equivalent activity Raeq ranges from 9.01 to 23.16 and is below the maximum recommended limit, i.e. 370 Bq kg-1. The annual gonadal dose equivalent has an average value of 75.62. The research in this study shows that all samples of corn have no biological hazard i.e. it was found that the natural levels of radioactivity are not within the high-risk range and are below the international standards. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Ionizing Radiation in Meat Processing and its Effects(VINČA INSTITUTE OF NUCLEAR SCIENCES, 2025-10); ; ; From a historical perspective, even in ancient times there was an awareness of the connection between food and human health. Hippocrates (460 BC), the father of medicine, emphasized that many diseases could be linked to diet, highlighting the idea that “let food be thy medicine and medicine be thy food.” This early recognition of the importance of safe and high-quality nutrition laid the foundations for later efforts to preserve food and protect it from harmful influences. Over the centuries, various preservation methods were developed, ranging from drying, salting, and smoking to modern technologies that include ionizing radiation as an effective way of extending shelf life and maintaining the nutritional properties of meat. This paper provides a overview of ionizing radiation in meat processing. The advantages of this technology are evident in the elimination of pathogenic microorganisms, the extension of shelf life, and the preservation of nutritional properties, while acknowledging the limitations that may occur at higher doses. The analysis encompasses microbiological, chemical, physical, and sensory aspects, along with relevant regulatory frameworks at both international and national levels. It is concluded that ionizing radiation offers considerable potential for improving food safety and sustainability in the food industry, but requires careful application and transparent communication with consumers. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, ASSESSMENT OF NATURAL RADIOACTIVITY LEVELS IN AGRICULTURAL SOIL AND TRANSFER IN RICE IN THE KOCHANI REGION, NORTH MACEDONIA(Faculty of Agriculture, University of East Sarajevo, Republic of Srpska, Bosnia and Herzegovina..., 2025-10-02); ; ; Soil can transfer radionuclides to plants which are subsequently consumed by humans. Sometimes their levels are so high that they are a concern for human health. Rice has an important share in the Macedonian diet, especially in the Kochani region, which is famous for its rice fields. Therefore, the main goal of this study was to measure the natural radioactivity in agricultural soil and rice crops in the Kochani region and to study the interaction between soil and rice by calculating the transfer factor (TF). The activity concentrations of 226Ra, 232Th and 40K were determined by using gamma spectrometry, i.e. a high purity germanium (HPGe) gamma-ray spectrometer. In agricultural soils, the mean activity concentrations of 226Ra, 232Th and 40K were 33.72 Bq kg-1, 37.62 Bq kg-1 and 152.90 Bq kg-1, while the mean activity concentrations of rice were 1.99 Bq kg-1, 2.51 Bq kg-1and 49.44 Bq kg-1, respectively. The world’s mean soil values of 226Ra, 232Th and 40K are 35, 30 and 400 Bq kg-1, respectively, hence these obtained values are lower compared to those obtained from research. This may be due to improved agricultural practices in the country and the geology of the area itself. However, we found that the radioisotopes have a heterogeneous distribution which must be caused by the nature and soil types in the area for which this study was conducted. However, the radioisotopes showed a heterogeneous distribution, likely influenced by the nature and soil types in the region. The mean transfer factors (TF) were very low for all samples, indicating a slow transport of these radionuclides to the rice grains. The results confirm that rice grown in these areas is safe for consumption. Further research on the TF across different rice varieties and geographical areas would allow for the development of predictive models for potential radiation exposure from rice consumption and help identify locations requiring additional monitoring. All mean transfer factors (TF) for the samples were very low, implying a very slow transport of these radionuclides to the rice grains. The obtained results make rice grown in these areas safe for consumption. By studying the TF among different rice varieties and geographical areas, researchers will be able to develop models to predict possible radiation exposure from rice consumption and locate activities or areas that require additional attention. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Raw food diets for pets: balancing health benefits and nutritional challenges(Faculty of Veterinary Medicine - Skopje, 2024-09-22); ; ; GEORGIEVSKI, SreckoRaw food diets, also known as BARF diets (Biologically Appropriate Raw Food), have gained popularity among pet owners seeking alternative feeding options for their dogs and cats. These diets aim to replicate the natural diet of wild animals, consisting of raw meat, bones, fruits, vegetables, and other unprocessed ingredients. Proponents of raw food diets claim several potential benefits, including improved digestion, enhanced dental health, shinier fur, healthier skin, and increased energy and vitality in pets. However, it is crucial to consider the associated risks of raw food diets. These risks include nutritional imbalances, bacterial contamination, choking hazards, and an increased risk of parasites. Consulting with a veterinarian or veterinary nutritionist is essential to ensure that a raw food diet is properly balanced and meets the pet's specific nutritional needs. Additional challenges include the higher cost and time required to prepare raw food diets compared to commercial pet foods. Pets may also develop allergies or sensitivities to specific ingredients, necessitating careful selection and monitoring. Furthermore, the long-term effects and benefits of raw food diets on pet health remain a topic of debate among veterinary professionals. Individual variations and medical conditions must be considered, as some pets may have specific dietary requirements or underlying health issues that make a raw food diet unsuitable. Not all pets thrive on a raw food diet, and individualized guidance is necessary to address any potential nutritional deficiencies or health concerns. Making an informed decision to feed a raw food diet requires careful consideration of both the benefits and risks, with the pet's overall well-being as the top priority. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, SCIENTIFIC AND REGULATORY PERSPECTIVES ON IRRADIATED FOOD: DETECTION STANDARDS AND SAFETY EVALUATION(Faculty of Agriculture, University of East Sarajevo, Republic of Srpska, Bosnia and Herzegovina..., 2025-10-02); ; ; ; Food irradiation is a scientifically validated and internationally endorsed technology that applies ionizing radiation to improve the microbiological safety and shelf life of food products. By effectively inactivating pathogens, parasites, and pests without significantly compromising nutritional or sensory quality, irradiation serves as a potent alternative to conventional decontamination methods. This review provides a comprehensive analysis of the scientific principles underlying irradiation, detailing the mechanisms of action, microbiological efficacy, toxicological safety, and minimal impact on nutritional value. These findings are supported by extensive evaluations from authoritative bodies, including the World Health Organization (WHO), the Food and Agriculture Organization (FAO), the International Atomic Energy Agency (IAEA), the European Food Safety Authority (EFSA), and the U.S. Food and Drug Administration (FDA). The paper also explores the regulatory landscape surrounding food irradiation, with particular focus on the European Union’s limited list of approved irradiated food categories under Directives 1999/2/EC and 1999/3/EC. The implications of regulatory fragmentation within the EU and the contrasts with countries such as the United States, Canada, India, and Thailand are assessed. Key applications, such as pathogen reduction in meat and poultry, insect control in spices and grains, and phytosanitary treatment for exportable fruits are discussed alongside economic and logistical benefits. Consumer perception remains a major barrier to widespread acceptance, often shaped by misconceptions and negative associations with the term “irradiation.” Strategies for effective communication, labeling transparency, and public education are examined. The review further assesses CEN (the European Committee for Standardization)-standardized and emerging detection methodologies critical for regulatory enforcement and traceability. Finally, it highlights the role of irradiation in advancing climateresilient food systems, reducing post-harvest losses, and supporting global food security, while calling for harmonized regulation and greater international cooperation.
