Sesium
radioaktif yang ditemui dalam ikan, air laut Jepun . . .
Kesan berbahaya sesium radioaktif telah
ditemui dalam ikan dan air laut di beberapa kawasan di Jepun, sebagai negara
terus untuk membahaskan sama ada ikan mereka adalah selamat untuk digunakan dan
protes anti-nuke berkembang ekoran bencana Fukushima.
Kementerian Pendidikan, Kebudayaan, sukan,
Sains dan Teknologi (MEXT) Jepun menyatakan bahawa radioaktif sesium, mungkin
daripada itu cacat tumbuhan I Fukushima nuklear, telah dijumpai dalam air laut
dan ikan dalam kawasan beberapa negara, berita agensi Rusia Itar-Tass
dilaporkan dari Tokyo. Radiasi akuatik telah dikesan di tengah Jepun (Shizuoka
Wilayah), bahagian barat pusat Honshu (Niigata) dan timur laut negara (Iwate).
Kepekatan zarah radioaktif adalah sangat
kecil dan tidak menjejaskan atau memberi risiko kesihatan kepada manusia, MEXT
berkata. Kementerian percaya bahawa sesium mungkin telah melakukan perjalanan
ke kawasan dalam hujan. Sesium radioaktif isotop radioaktif buatan manusia yang
dihasilkan melalui pembelahan nuklear unsur sesium. Ia mempunyai separuh hayat
30 tahun, menjadikannya amat-amat toksik.
Awal tahun ini, tahap rendah radioaktif
sesium telah ditemui dalam ikan tidak jauh dari pantai timur Jepun, yang
dipercayai berasal dari kilang Fukushima. Kementerian terus memantau dan
mengesahkan kesan radiasi dalam air laut dan ikan berikutan bencana nuklear 2011
di kompleks Fukushima-Daiichi.
Sejauh manakah selamatnya ikan dan makanan
laut Jepun? Banyak negara terhad import makanan mereka dari Jepun berikutan
malapetaka ini. India telah menggantung import makanan dari Jepun selama 3
bulan pada bulan April 2011, kerana bimbang pencemaran radioaktif. EU
mengenakan kawalan radiasi yang lebih ketat ke atas import makanan dan makanan
haiwan dari Jepun.
Sejauh penuh penyebaran pencemaran
radioaktif di Jepun masih tidak jelas. Penemuan ikan dan Jepun radioaktif air
laut boleh merosakkan lagi industri makanan laut lesu Jepun. Laporan makanan
laut yang tercemar adalah membimbangkan bagi negara ini, kerana air laut yang
tercemar dan bergerak ikan di laluan yang tidak terkawal dan tidak bisa
dikesan.
Tahap-tahap rendah radiasi nuklear dari
bencana Fukushima dikesan dalam tuna bluefin di luar pantai California pada
bulan Mei tahun ini, menunjukkan ikan yang membawa bahan-bahan di seluruh
Lautan Pasifik lebih cepat daripada angin atau air. Penyelidik Amerika Syarikat
yang dijalankan satu kajian yang menunjukkan tuna bertanggungjawab untuk
mengangkut radionuklid dari bencana Fukushima 2011 merentasi seluruh Lautan
Pasifik Utara.
Banyak soalan sama ada ikan dari Lautan
Pasifik dan perairan pantai Jepun adalah selamat untuk dimakan berikutan
bencana Fukushima. Pegawai Jepun dan ramai saintis mereka berkata, tetapi data
mengenai tahap radiasi dalam stok ikan Jepun memberitahu cerita yang berbeza.
Tahap radiasi yang tinggi pada banyak spesis bahawa Jepun telah eksport ke
Kanada pada tahun-tahun kebelakangan ini, seperti ikan kod, tunggal, semacam
ikan pecak, kokanee daratan, kakap, trout dan belut. Dan tahap radiasi dalam
spesis tertentu adalah lebih tinggi tahun ini berbanding pada tahun 2011,
laporan Straight.com Vancouver.
Itu tahap tertinggi sesium dalam ikan telah
dikesan Mac, setahun selepas kemalangan, apabila 1 salmon masu daratan yang
terperangkap dalam sungai Jepun telah dijumpai 18700 Becquerel kilogram per
sesium, atau 187 kali had undang-undang Jepun untuk radiasi dalam makanan laut.
(Becquerel unit radioaktif yang sama di mana satu mereput nukleus sesaat).
Tim Takaro, merupakan Profesor Madya di
Universiti Simon Fraser, kini mengelakkan makan ikan dari Jepun: "Saya
akan mencari sumber lain untuk ikan jika saya fikir ia adalah dari kawasan
itu," katanya kepada Straight.com. "Terdapat terlalu banyak soalan
dan jawapan yang tidak cukup untuk mengatakan semuanya adalah baik."
Takaro adalah ahli kumpulan Pakar anti-nuklear Kanada Untuk Hidup Global.
Tragedi Fukushima telah berkecai suci Jepun

Radioactive
cesium found in Japan’s fish, seawater . . .
Harmless traces of radioactive cesium have
been discovered in fish and seawater in several areas of Japan, as the country
continues to debate whether their fish is safe to consume and anti-nuke
protests grow in the wake of the Fukushima disaster.
Japan’s Ministry of Education, Culture,
Sports, Science and Technology (MEXT) stated that radioactive cesium,
presumably from the crippled Fukushima I nuclear plant, was found in seawater
and fish in several regions of the country, Russian news agency Itar-Tass
reported from Tokyo. The aquatic radiation was detected in central Japan
(Shizuoka Prefecture), the western part of central Honshu (Niigata) and the
country’s northeast (Iwate).
The concentrations of radioactive particles
are very small, and pose no health risks to humans, MEXT said. The ministry
believes that cesium may have traveled to the area in rainfall. Radioactive
cesium is a human-made radioactive isotope produced through the nuclear fission
of the element cesium. It has a half-life of 30 years, making it extremely
toxic.
Earlier this year, low levels of
radioactive cesium were found in fish just off Japan’s east coast, which was
believed to have originated from the Fukushima plant. The Ministry continues to
closely monitor and verify traces of radiation in seawater and fish following
the 2011 nuclear disaster at the Fukushima-Daiichi complex.
How safe is Japan’s fish and seafood? Many
countries restricted their food imports from Japan in the wake of the
catastrophe. India suspended food imports from Japan for three months in April
2011, fearing radioactive contamination. The EU imposed tighter radiation
controls on its imports of food and animal feed from Japan.
The full extent of the spread of
radioactive contamination in Japan remains unclear. The discovery of
radioactive Japanese fish and seawater could further damage Japan's flagging
seafood industry. Reports of contaminated seafood are worrisome for the
country, since contaminated seawater and fish move in uncontrollable and
untraceable paths.
Low levels of nuclear radiation from the
Fukushima disaster were detected in bluefin tuna off the California coast in May of this year, suggesting that
fish are carrying the contaminants across the Pacific Ocean faster than wind or
water. US researchers carried out a study showing the tuna were responsible for
transporting radionuclides from the 2011 Fukushima disaster across the entire
North Pacific Ocean.
Many question whether fish from the Pacific
Ocean and Japan’s coastal waters are safe to eat in the wake of the Fukushima
disaster. Japanese officials and many scientists say they are, but the data on
radiation levels in Japan’s fish stock tells a different story. Radiation
levels are high in many species that Japan has exported to Canada in recent
years, such as cod, sole, halibut, landlocked kokanee, carp, trout and eel. And
radiation levels in certain species are higher this year than in 2011,
Vancouver’s Straight.com reports.
The highest levels of cesium in fish were
detected in March, a year after the accident, when a landlocked masu salmon caught
in a Japanese river was found to have 18,700 Becquerel of cesium per kilogram,
or 187 times Japan’s legal limit for radiation in seafood. (A Becquerel is a
unit of radioactivity equal in which one nucleus decays per second).
Tim Takaro, an associate professor at Simon
Fraser University, now avoids eating fish from Japan: “I would find another source for fish if I
thought it was from that area,” he told Straight.com. “There are way too many questions and not
enough answers to say everything is fine.” Takaro is a member of
the Canadian anti-nuclear group Physicians for Global Survival.
The Fukushima tragedy has shattered
Japanese faith in the country’s decades-long reliance on nuclear energy, with several
large anti-nuclear demonstrations taking place in the country in
recent months.
