Concerned about the possible negative impact of radiation spewed by the Fukushima No. 1 nuclear plant on their children's heath, mothers in their 20s who work as fashion models have begun studying the issue to raise awareness among other moms of their generation.

Representing some 300 members across Japan of the Mamacawa (Cute Mom) Project, which promotes educational activities of young mothers, the models recently took part in study sessions on practical ways to protect their children from the adverse effects of radiation.

They also held talks with an award-winning U.S. film director who has made documentaries about children affected by the 1986 Chernobyl nuclear disaster.
