Discovery of Uranium Compounds that Do Not Dissolve in the Stomach

Russian researchers from Moscow State University have made a groundbreaking discovery in the field of radioactive materials. They have found uranium compounds that do not dissolve in the stomach, providing valuable insights into the calculation of radiation doses and the control of contamination in high radioactivity areas.

Calculating Indoor Dose and Controlling Contamination

The data obtained from the research will play a crucial role in accurately calculating the indoor dose of radiation for both humans and animals. This information will aid in the effective control of contamination in areas with high levels of radioactivity, ensuring the safety of individuals and the environment.

Tracing the Behavior of Uranium Compounds

The scientists at Moscow State University traced the changes in the structure of uranium compounds within the human body. Surprisingly, some compounds managed to maintain their solid shape even in the stomach. The researchers used model fluids that replicated the components of the human gastrointestinal tract and lung fluids to study the behavior of these compounds.

Unexpected Results

The results of the study revealed unexpected behavior of certain uranium compounds. For instance, highly soluble uranium oxide UO3 remained solid in the gastric environment. Additionally, the oxides UO2.05 and U3O8 showed increased organization in their crystal lattices over a specific period of time. These findings shed light on the activity and stability of uranium compounds in different organs.

Advanced Analytical Techniques

The scientists employed state-of-the-art selective methods in X-ray absorption and spectrum processing technology to study changes within the crystal lattice of uranium compounds. This advanced analytical approach enabled them to track shifts in the structure of U4O9 oxide in the lung environment, where it transformed into a more stable version.

Implications for Radiation Exposure

The obtained data will contribute to the accurate calculation of internal radiation exposure doses. Furthermore, it will aid in effectively managing the level of contamination in high radioactivity areas. The researchers plan to expand their study by examining the transformation of oxides in real bodies and environments, including bovine serum, to gain a comprehensive understanding of the effects of radionuclides on living organisms.
