Radioisotope Dilution Technique for Determination of Vitamin B12 in Foods [PDF]
Journal of AOAC INTERNATIONAL, 1982 Abstract A radioisotope dilution (RID) method for the determination of vitamin B12 is presented. The method combines a standard extraction procedure (AOAC 43.108,12th ed.) with a commercially available RID assay kit. The method was evaluated on a wide range of fortified and unfortified food products.

Annales de recherches veterinaires. Annals of veterinary research, 1985 Serum vitamin B12 from 6 sheep fed a diet containing 0.06 mg cobalt per kg dry matter (DM) was analysed by a radioisotope dilution (RID) technique. The results were compared with values obtained by a microbiological method (Lactobacillus leichmannii - ATCC 7830) specific for "true" vitamin B12.

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
