9/11～12,International “Expert” symposium was held in Fukushima medical university. (Link)
“Mr.100mSv” Yamashita Shunichi attended this symposium as well.
In this symposium,they mentioned the risk of internal exposure and they stated like this below.(Page 1-3)
In addition to actual effects,imaginary impact has been enormous.Often exaggerated stories regarding effects of internal exposure was provided to general public to lead misunderstanding that the effect from internal exposure is much severer than that from external exposure.In the current radiation protection system,a dose from internal exposure is expressed as a committed dose,an integral over 50 years for adult and years until 70 years of age for children.The committed dose is added up with an external dose to give an effective dose.Once expressed as the effective dose,from the viewpoint of radiation protection,the effect is supposed to be the same no matter whether the exposure is external or internal.The experts on biological effects of radiation and radiation protection should provide precise information on the concept of internal exposure to the public.
This is what they are trying to do for the human-beings.
In addition to the impact of this statement,the “expert” who stated this,Sakai Kazuo,is a member of Nuclear disaster protection team under Japanese cabinet.
He specializes in hormesis,which is the radioactive effect to “improve your health”.
In the concept of hormesis,they think radiation improves your immune system or make plants grow faster and bigger. cf.Godzilla
In 2006, WHO stated hormesis has no basis, now it is considered to be a joke “science”.
Whether it is a joke or not,hormesis admits the impact of radiation,which contradicts its main premise.
A private institution, Citizen’s Radioactivity Measuring Station, has sent an inquiry against the symposium.
