The Japanese government posts space radiation doses in Tokyo, Fukushima, and Seoul on the Japanese embassy website in Korea.

The Japanese government has posted the radiation doses of Tokyo, Fukushima and Seoul on the website of the Japanese Embassy in Korea.

Since there was no English page yet, I made an English page using Google Translate without permission.

韓国の日本大使館のホームページに東京と福島とソウルの空間放射線量の数値を掲載する事になりました。

まだ英語版のページが無かったので、勝手ながらGoogle翻訳を駆使して英語のページを作りました。

The amount of space radiation is lower in Tokyo than in Seoul.

空間放射線量はソウルよりも東京の方が低いです。

In Fukushima City, the radiation dose is still high.

However, in Tokyo, it is a low value without any problems.

The amount of space radiation in Tokyo is less than 1/3 of Seoul.

You can come to Tokyo for business and sightseeing with peace of mind!

福島市では、空間放射線量は依然として高いです。

ですが、東京では問題の無い低い数値となっています。

東京の空間放射線量は、ソウルの1/3以下の値です。

皆さんは安心して東京に旅行に、そして観光に来ることができますよ！

What is the actual space radiation dose in each region?

各地の実際の空間放射線量はどのくらい？

I will quote the website of the Japanese Embassy.

日本大使館のホームページを引用させて頂きます。

As shown below, the air dose rates in the following three cities in Japan are comparable to those in major cities overseas including Seoul.

The radiation dose in the environment varies depending on the weather (Note).

The Government of Japan will continue to provide accurate information based on scientific evidence and will explain it transparently and carefully.

I hope that the understanding of the Korean people will deepen.

* Data from other locations can also be viewed from the above websites.

(Note) Normally, the air dose rate measured is due to natural radiation from the earth, etc., but the radiation comes from natural radioactive materials present in the walls, floors, and ceilings of buildings.

Is also out. For example, the amount of radiation in buildings and tunnels is greater than that in the outside, and in urban areas where there are many concrete buildings outside, the air dose rate

The value of may be slightly higher. In addition, when it rained, dust drifting in the air was dropped on the surface by rain, and as a result,

Short-lived natural radioactive materials (Lead-214: half-life about 27 minutes, bismuth-214: about 20 minutes, etc.) will be collected on the ground.

As a result, the air dose rate may temporarily increase on rainy days.

Let’s enjoy your trip to Japan!

Japan has been freed from radiation concerns!

Actually, the amount of space radiation is measured regularly to confirm that it is below the standard.

We are looking forward to seeing you in Japan for sightseeing and business!
