Determination of isotopic ratio of сalcium by gamma activation analysis and free radical oxidation of lipids in normal and cancerous tissues of thyroid gland

Abstract

Chemiluminescence and gamma activation analysis was used to determine the isotopic ratio of calcium in normal, non-malignant and cancerous tissues of thyroid gland. This result was used for diagnostics of cancerous thyroid gland morbidity. The high value of isotopic ratio ⁴⁴Ca/⁴⁸Ca in paratumor tissues of thyroid gland has allowed concluding about significance of transmembrane circulation calcium.
