Re: Lancet Dec. 8th abstract - Chernobyl thyroid cancer incidence

[Mike Lantz <mlantz33@CYBERTRAILS.COM>]

"However, scarcity of reliable estimates of individual thyroid dose has hindered conclusions

about the exact effect of the Chernobyl accident on thyroid glands in children."



"The major difference in background was that children in group I (born after the accident;

0.00%) were not exposed to fallout, whereas those in groups II (Born within months; 0·04%) and

III (born before; 0.32%) were probably exposed to fallout in utero or directly, respectively."







I've read the article now; thanks for the link.  Their results would imply that "in utero"

photon exposure or the uptake of radioiodine to a developing fetus is an insignificant

effect;  that only young infants were affected by the accident.   Does that make sense?
