Objective: The objective of this study is to examine the performance of new generation protection aprons as alternative to conventional lead aprons regarding their radiation protection effectiveness.
Method And Materials: Radiation protection aprons made of lead-containing and lead-free materials from a total of seven companies were compared. Furthermore, different lead equivalent values of 0.25, 0.35 and 0.5 mm were compared. For quantitative assessment, radiation attenuation was determined with increasing voltage in steps of 20 kV from 70 kV up to 130 kV.
Results: New generation aprons and conventional protection lead aprons showed a similar shielding performance at lower tube voltages below 90 kVp. When tube voltage was increased above 90 kVp, significant (p < 0.05) differences between the three apron types were observed, with conventional lead material as best shielding performer over lead composite and lead-free aprons.
Conclusion: We observed a similar radiation protection performance between conventional lead aprons and new generation aprons at low intensity radiation workplaces, with lead aprons being dominant for all energies. Only new generation aprons of 0.5 mm thickness would adequately replace 0.25 and 0.35 mm conventional lead aprons. For healthy radiation protection, the possibility of using weight-reduced X-ray aprons is very limited.

The global challenge of wastewater contamination, especially from persistent pollutants like radioactive isotopes and heavy metals, demands innovative purification solutions. Radioactive iodine isotopes (I and I), stemming from nuclear activities, pose serious health risks due to their mobility, bioaccumulation, and ionizing radiation, particularly impacting thyroid health. Similarly, hexavalent chromium, Cr(VI), is highly toxic and persistent in water, linked to cancer and other severe health issues.

The Space Radiobiological Exposure Facility (SREF) is a general experimental facility at the China Space Station for scientific research in the fields of space radiation protection, space radiation biology, biotechnology, and the origin of life. The facility provides an environment with controllable temperatures for experiments with organic molecules and model organisms such as small animals, plant seeds, and microorganisms. The cultivation of small animals can be achieved in the facility with the use of microfluidic chips and images and videos of such experiments can be captured by microscopy.

Vaccination may cure cancer patients by inducing tumor-specific immune responses. Radiotherapy is an appealing strategy to generate cancer vaccines in situ; thus far, however, only modest and short-lived immune responses are achieved. We here show that radiation combined with co-activating STING-TLR9 can generate powerful in situ cancer vaccines.

Purpose: Continuous advancements in cancer management have resulted in increased long-term survival rates amongst cancer survivors and in turn have exposed the full extent of radiotherapy-associated morbidities. Radiation-induced coronary heart disease (RICHD) is one of the leading causes of morbidity and mortality in cancer survivors, particularly in those having undergone mediastinal radiation. While mediastinal radiation has been shown to substantially reduce both recurrence and mortality rates in multiple thoracic malignancies, the risk for the development of RICHD is of significant concern.

The lack of effective protection against UVB radiation, that severely disrupts the metabolism of keratinocytes, underlines the search for bioactive compounds that would provide effective protection without causing side effects. Therefore, the aim of the study has been to assess the effect of two compounds, that are different in terms of structure and properties: 3-O-ethyl ascorbic acid-EAA (a stable derivative of vitamin C) and cannabigerol-CBG, used separately or concurrently, on the metabolism of keratinocytes previously exposed to UVB. The obtained results indicate diverse, yet mutually reinforcing localization of the tested compounds, both within the membrane structures and cytosol.
