What is hydrogen bomb?
The “hydrogen bomb” which North Korea claimed to succeed in testing in nuclear test,
what sort of thing is it?
Following the nuclear test, on 3rd Sept, at the Nagasaki Atomic Bomb Museum of Hiroshima City,
indicating the number of the days since the last nuclear test
the “peace clock” was reset for the first time in 359 days,
it became “0 day”.
North Korea which conducted nuclear test again in less than one year.
This time it claimed that it “succeeded in hydrogen bomb test”.
“H-bomb” (two kanji) is the abbreviation of hydrogen bomb (four kanji).
Atomic bomb, so-called “A-bomb” is
to compress the nuclei of plutonium or uranium with gunpowder,
and the energy incurred during “nuclear fission” is used,
while “H-bomb” is to make hydrogen atoms to collide and cause “nuclear fusion”,
in other words, the energy incurred when atoms adhere is used.
In hydrogen bomb, there is also occasion of
using the heat and impact incurred by atomic bomb detonation as initiator
to cause nuclear fusion.
Compared with nuclear fission, nuclear fusion produces greater energy,
In general the power of hydrogen bomb
is said to be several time to hundred times over that of atomic bomb.
Looking at the photo of Chairman Kim inspecting the hydrogen bomb
the hydrogen bomb is made in shape like a gourd.
According to experts, first of all the atomic bomb is detonated,
after that, in the inner part, with the nuclear fusion of hydrogen atoms
the second explosion occurs.
At last the entire container is said to explode.
The scale of explosion
seems can be adjusted by a device connected to a cord.
This is said to be a typical structure of hydrogen bomb which has also been developed by countries such as the US and Russia.
The power of atomic bomb explosion and hydrogen bomb
is expressed in energy unit “kiloton”,
the power of the atomic bomb dropped on Hiroshima 72 years ago was 16 kiloton,
the atomic bomb dropped on Nagasaki was 21 kiloton.
The power of the explosion caused during the hydrogen bomb test of North Korea on 3rd Sept,
according to the Ministry of Defense, is estimated to be 70 kiloton,
which is over 4 times the power of the bomb on Hiroshima.
North Korea which repeats launching missiles and nuclear tests.
These two actions are considered as “set” to achieve certain purpose.
What has to be paid attention to is this photo.
The thing seen behind looks like the tip of a missile.
It looks like a size that the gourd-shaped hydrogen bomb can fit in.
The Ministry of Dense of South Korea sees that
the technology of North Korea on “miniaturising” the nuclear warheads
“has reached a considerable level”.
With the tip of the missile loading a miniaturised nuclear warhead
while it can fly till the east coast of the US,
the threat of North Korea will become increasingly stronger.
