東大病院放射線治療チーム @team_nakagawa

We are the doctors and medical physicists in radiation oncology group at The University of Tokyo Hospital.

東大病院放射線治療チーム @team_nakagawa

Our team has been organized to share the knowledge of medicine regarding the accident in Fukushima of nuclear power plants.

東大病院放射線治療チーム @team_nakagawa

I am Keiichi Nakagawa, who is a director in radiation oncology at The University of Tokyo Hospital.

東大病院放射線治療チーム @team_nakagawa

I express deeply sympathy for the stricken people in Tohoku and Kanto massive earthquake area.

東大病院放射線治療チーム @team_nakagawa

I‘d like to make a tweet on current leak at Fukushima nuclear power plants.

東大病院放射線治療チーム @team_nakagawa

Radiation itself is a light (a photon) or a particle which has an energy allowing to go through materials.

東大病院放射線治療チーム @team_nakagawa

If we receive it too much, it causes substantial damages on body and its gene.

東大病院放射線治療チーム @team_nakagawa

We call an ability to emit a radiation “radioactivity”, and call a material embeded radioactivity “a radioactive material”.

東大病院放射線治療チーム @team_nakagawa

Under current accident of nuclear plants, radioactive materials leaked out. It looks like Cedar hay flies spread in the air.

東大病院放射線治療チーム @team_nakagawa

The difference is that this material has the radioactivity.

東大病院放射線治療チーム @team_nakagawa

Suppose what is effective to prevent Cedar hay coming into your house. First is to flap away it from your cloth before inside your house.

東大病院放射線治療チーム @team_nakagawa

To shut the windows to seal is also effective.

東大病院放射線治療チーム @team_nakagawa

In contract, a radiation can go through walls and windows; therefore there is no way to prevent all radiations coming into basically.

東大病院放射線治療チーム @team_nakagawa

We can easily understand that if you breathe radioactive materials into your body, it would make a serious situation.

東大病院放射線治療チーム @team_nakagawa

We call an exposure receiving inside body “internal exposure”.

東大病院放射線治療チーム @team_nakagawa

It is more dangerous than “external exposure” which comes from outside body.

東大病院放射線治療チーム @team_nakagawa

The main reason is that we can wash out those materials outside body while we cannot do it in case inside body.

東大病院放射線治療チーム @team_nakagawa

When you go home with much amount of radioactive materials, it is important to flap away them from your cloth and wash your body.

東大病院放射線治療チーム @team_nakagawa

There was an opinion that closing the window is not useful. This opinion is totally misunderstanding.

東大病院放射線治療チーム @team_nakagawa

Closing the windows is greatly effective.

東大病院放射線治療チーム @team_nakagawa

If there are somethings to prevent, radioactive materials cannot come in, and also the radiation reduces before it reaches in your body.
