FUKUSHİMA NÜKLEER AFETİNİN ARDINDAN TELLURIUM-129m (129mTe) ZEMİN BİRİKTİRME ÇALIŞMASI: İSTATİSTİKSEL İŞLEM TEKNİKLERİ KULLANILARAK UNSCEAR VERİTABANININ TANIMLAYICI ANALİZİ

Son zamanlarda dünyayı etkileyen en şok edici kazalardan biri, büyük bir depremin ardından Fukushima-Daiichi nükleer Son zamanlarda dünyayı etkileyen en şok edici kazalardan biri, büyük bir depremin ardından Fukushima-Daiichi nükleer santralinin yıkılması ve ardından doğu kıyı bölgesini etkileyen 15 metrelik güçlü bir Tsunami dalgasıydı. Bu felaket olayının en büyük olumsuz sonuçlarından biri, radyoaktif maddelerin çevredeki ortamda salınması ve yayılmasıdır. Tellurium- 129m, toprakta radyoaktivite birikimini ölçerek yayılmanın büyüklüğünü değerlendirmek için kapsamlı bir şekilde izlenen fisyon ürünlerinden biridir. Radyasyon seviyesi/konum ilişkisi çalışması, radyoaktivitede ani artış gösteren Birleşmiş Milletler Atomik Radyasyonun Etkileri veri tabanı için benzersiz İstatistiksel Proses Kontrol metodolojileri kullanılarak basit ve ucuz bir istatistiksel yazılım paketi kullanılarak test edildi. Numune alma noktaları, radyoaktivite seviyesi ile coğrafi olarak ilişkilendirildi ve maksimum radyonüklid konsantrasyonunun bulunduğu nokta, hasarlı bitki konumu ile ilişkilendirilebilir. Ölçülen radyoaktivitenin beşte üçünden fazlası, Namie ve Futaba kasabaları, Litate köyü ve Iwaki şehri olmak üzere beş belediyeyi kapsayan yaklaşık 640 km2'lik bir alanla sınırlıdır. Enlem odaklı grafik, birikimde ani bir artış ve ardından kademeli bir düşüş gösterdi. Felaket olayının olduğu bölgede aşırı Tellurium-129m aktivitesi gözlemlenebilir.

STUDY OF TELLURIUM-129m (129mTe) GROUND DEPOSITION FOLLOWING FUKUSHIMA NUCLEAR DISASTER: DESCRIPTIVE ANALYSIS OF UNSCEAR DATABASE USING STATISTICAL PROCESS TECHNIQUES

One of the most shocking accidents that have impacted the world recently was the devastation of the Fukushima-Daiichi nuclear power plant following a major earthquake followed by a strong 15-meter Tsunami wave affecting the east coast region. One of the major adverse consequences of this catastrophic event is the release and dissemination of radioactive materials in the surrounding environment. Tellurium-129m is one of the comprehensively traced fission products to assess the magnitude of spreading by measuring ground soil deposition of radioactivity. Radiation level/location relationship study was tested using a simple and inexpensive statistical software package using unique Statistical Process Control methodologies for the United Nations Scientific Committee on the Effects of Atomic Radiation database that demonstrated spiking in radioactivity. Sampling points were geographically associated with the radioactivity level with the spot of the maximum radionuclide concentration could be linked with the damaged plant location. More than three-fifths of the measured radioactivity are confined in an area of about 640 km2 covering five municipalities namely Namie, and Futaba towns, Litate village and Iwaki city. The latitude-oriented chart showed a sudden rise in deposition followed by a gradual decline. Excessive Tellurium-129m activity could be observed in the area of the catastrophic event.
