Main results of in vitro studies linking ICM with X-rays to DNA damage

Experimental model	Effect
Cell types (lymphocytes)	DNA damage increased from 30% to 200%
ICM without X-rays	No effect
ICM added after X-rays	No effect
ICM pre-irradiated before mixing with blood	No effect
ICM irradiated with gamma rays	No effect
Increasing concentrations of iodine	Linear dose-dependent effect
Different ICM brands or manufacturers	No difference (only iodine concentration counts)
