Dosimetry for the TRIO (parents + child) Study
Radiation gonadal dose for the subjects of the TRIO study includes three components:
- Dose from external irradiation during the cleanup mission at the Chernobyl site;
- Dose from external irradiation during residence in the town of Pripyat between the time of the accident and evacuation; and
- Dose from external irradiation and ingestion of long-lived cesium isotopes (134Cs and 137Cs) in local food during residence at contaminated locations after completion of the cleanup mission and/or evacuation from the town of Pripyat.
The preliminary parental gonadal dose from all exposure pathways among the first 50 trios averaged around 300 mGy, ranging from essentially zero to 4,300 mGy. For the majority of families, parental exposure mainly occurred during the cleanup mission at the Chernobyl site.
