In Germany, personal electronic dosemeters (AEPDs) are presently applied mainly for operational radiation protection monitoring particularly in nuclear power engineering companies, large hospitals and research centres. This is done in addition to the official dosimetry of record. Therefore, frequently, double monitoring occurs-officially and operationally. A crucial advantage of AEPDs compared with passive dosemeters is the ability to adapt the monitoring period to the working time in controlled areas and to allow an immediate readout of the dose after leaving the controlled area, e.g. a job-related monitoring is possible by correlating the readout dose with the job performed. Germany started a general research project, consisting of two parts, for an optimised implementation of personal electronic dosemeters into official dosimetry. The use of AEPDs as official dosemeters depends on an approval by Federal and Federal State ('Länder') authorities as an official dosimetry system, which has to comply with special requirements ensuring that the legal requirements are fulfilled. The formulation of these special requirements is in the focus of part one of the research project, supervised by the Federal Office for Radiation Protection (BfS) and performed by the Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) mbH. As a result of part one, a framework was developed which is the basis for a future technical implementation project. Part one is described in the paper, while part two is still to be initiated and will deal with the implementation and testing phase of the introduction of personal electronic dosemeters as official dosemeters.

The wild edible plants offer a valuable resource for food and human nutrition. The current study aimed to analyze the proximate composition and ethno-medicinal profiles of twenty selected wild edible plants from the Malakand District, Pakistan. The proximate composition (moisture, ash, crude protein, crude fat, and dietary fiber) was analyzed following Association of Official Agricultural Chemists (AOAC) protocols.

Article Synopsis
- Clinical imaging techniques like PET combined with CT are becoming more common in biomedical research with small animals, but handling radioactive substances requires strict regulations and training to ensure safety.
- This paper outlines the requirements set by the Radiation Protection Act and associated regulations, with a focus on practical steps in PET/CT imaging, from receiving radiopharmaceuticals to waste disposal.
- An analysis of radiation doses over four years in a small animal imaging facility showed that personnel exposure is generally lower than in human PET/CT imaging, remaining well within legal limits.
Establishment of an absolute measurement of the reference air kerma rate for HDR Ir brachytherapy sources.

School of Science, Hebei University of Science and Technology, Shijiazhuang, China.
Purpose: Before this study, no institution in China had undertaken the calculation and official establishment of reference values for the reference air kerma rate associated with high-dose rate Ir sources used in brachytherapy. This research, carried out at the National Institute of Metrology (NIM) in China, has successfully established an Ir reference radiation facility. Consequently, it has achieved the absolute measurement of the reference air kerma rate for high-dose rate brachytherapy using Ir sources.

In the United States, the Federal Aviation Administration has officially classified flight crews (FC) consisting of commercial pilots, cabin crew, or flight attendants as "radiation workers" since 1994 due to the potential for cosmic ionizing radiation (CIR) exposure at cruising altitudes originating from solar activity and galactic sources. Several epidemiological studies have documented elevated incidence and mortality for several cancers in FC, but it has not yet been possible to establish whether this is attributable to CIR. CIR and its constituents are known to cause a myriad of DNA lesions, which can lead to carcinogenesis unless DNA repair mechanisms remove them.

Article Synopsis
- A study developed a deep learning model using whole-body low-dose CT scans to predict cytogenetic abnormalities in multiple myeloma patients, which are crucial for determining risk levels.
- The data included 151 patients and was analyzed based on specific genetic markers, showing the model performed best for certain abnormalities, with survival rates indicating the effectiveness of the predictions.
- The results suggest that this deep learning model can accurately classify cytogenetic abnormalities, offering a promising tool for risk stratification in multiple myeloma management.
