[Radioprotective effect of "light" water: doubtful validity]
Summary
This study questions the claimed radioprotective and immune-boosting effects of "light" water, suggesting potential microelement deficiency from its consumption. The benefits of reduced deuterium and 18O isotopes are deemed unlikely.
Area of Science:
- Biochemistry
- Radiochemistry
- Immunology
Context:
- Recent publications suggest "light" water, with reduced deuterium and 18O isotopes, possesses radioprotective and immunopotentiating properties.
- The scientific basis for these claimed effects requires rigorous evaluation.
Purpose:
- To critically assess the validity of reported radioprotective and immunopotentiating effects attributed to "light" water.
- To compare the effects of "light" water with water purified of a specific microelement.
Summary:
- Investigations comparing "light" water to microelement-purified water raise concerns.
- Prolonged consumption of "light" water may lead to essential microelement deficiency.
- The purported benefits of reduced stable isotopes (deuterium, 18O) in water are considered unlikely.
Impact:
- Highlights the potential risks of consuming "light" water, specifically microelement deficiency.
- Challenges unsubstantiated claims regarding the health benefits of isotopically depleted water.
- Emphasizes the need for evidence-based research in evaluating water's biological effects.

Mutations
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

Biological Effects of Radiation
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...
Absorption of Radiation
The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:
