A reactor at a nuclear power plant in Chernobyl, Ukraine exploded on April 26, 1986. Chernobyl (Sebuah reaktor di pembangkit listrik tenaga nuklir di Chernobyl, Ukraina meledak pada tanggal 26 April 1986.)

According to a report carried out by the BBC, the explosion released at least 100 times more radiation than the atomic bombs detonated in Hiroshima and Nagasaki in 1945. (Menurut Laporan yang dilakukan oleh BBC, ledakan tersebut melepaskan radiasi setidaknya 100 kali lebih banyak dari atom bom meledak di Hiroshima dan Nagasaki pada tahun 1945.)

On 25 April, prior to a routine shutdown, the reactor crew at Chernobyl 4 began preparing for a turbine test, but the power from the turbine ran down too rapidly, so new voltage regulator designs were to be tested. (Pada 25 April, sebelum penghentian rutin (pemeliharaan rutin), kru reaktor di Chernobyl 4 mulai mempersiapkan turbin uji( (menguji apakah reactor masih dapat didinginkan jika pembangkit kehilangan daya)), tetapi ternyata daya dari turbin turun terlalu cepat, jadi desain regulator tegangan baru harus dicoba.

A series of operator actions, including the disabling of automatic shutdown mechanisms, preceded the attempted test early on 26 April. (Serangkaian tindakan operator, termasuk penonaktifan mekanisme pematian otomatis, didahului test pegujian lebih awal pada tanggal 26 April.)

By the time that the operator moved to shut down the reactor because it was in an extremely unstable condition. (Pada saat itu operator berpindah mematikan reaktor karena itu dalam kondisi yang sangat tidak stabil.)

The steam generator then exploded and released fission products to the atmosphere. (Pembangkit uap tersebut kemudian meledak dan mengeluarkan produk fisi/pemecahan ke atmosfer.)

About two to three seconds later, a second explosion threw Out fragments from the fuel channels and hot graphite.(Sekitar dua sampai tiga detik kemudian, ledakan kedua melemparkan pecahan dari saluran bahan bakar dan grafit panas.)

Two workers died as a result of these explosions. (Dua pekerja tewas akibat ledakan tersebut.)

The graphite and fuel became incandescent and started a number of fires, causing the main release of radioactivity into the environment. (Grafit dan bahan bakar menjadi pijar dan memulai sejumlah kebakaran, menyebabkan pelepasan utama radioaktif ke lingkungan.)

The city of death

A large amount of radioactivity was released, over half of it being from biologically-inert noble gases.(Banyaknya radioaktif dilepaskan, karena hujan es itu berasal dari gas mulia/inert secara biologis.)

Two individuals died on the day of the explosion, followed by an additional 29 deaths due to radiation in the weeks following the accident. (Dua orang meninggal pada ledakan hari itu, diikuti oleh 29 kematian tambahan karena adanya radiasi berminggu – minggu setelah insiden itu.)

However, to this day the long-term effects of the explosion in the form of cancers and physical and mental deformities resulting from radiation exposure are still being accounted for. (Namun, hingga hari ini ledakan tersebut menimbulkan efek jangka panjang baik berupa kanker maupun fisik kelainan mental akibat paparan radiasi masih diperhitungkan.)
