Abstract

Metaphase chromosome analysis of lymphocytes is the gold standard for biodosimetry to estimate the levels of radiation exposure in various animals as well as humans. Animals, including experimental, companion, and wild animals, are powerful and indispensable models for researching radiation injury, safety, and therapy. Moreover, biodosimetry of animal models can be used to support human biodosimetry data and may be useful for estimating environmental contamination by radioactive materials. The basic restraint procedure and venipuncture technique are different depending on each animal type. The general procedure evaluating metaphase chromosomes is similar to the human blood technique except for a minor modification in the initial culture. This chapter will introduce basic mouse, rat, rabbit, dog, cat, cow, horse, goat, pig, and wild boar venipuncture and blood sampling techniques for metaphase chromosome preparation and analysis.
