A cikin nazarin ruwa Ta Cibiyar Hanzarta ta Kasa (CNA), an gano adadin uranium-236 wanda ya wuce kashi 2,5 na sauran yankuna masu kama da wannan latitude.
An buga wannan binciken a cikin mujallar Kimiyya na Muhallin Mujallar kuma ya binciki matakan wannan isotope na rediyo a tashar teku ta DYFAMED da ke Ligurian Sea, wani yanki na Bahar Rum wanda ke tsakanin Riviera na Italiya da tsibirin Corsica.

Muna fuskantar isotope na rediyo wanda yake da aprabin rayuwa na shekaru miliyan 23,4 kuma cewa shi rediyo ne na roba, wanda ba shi da asali a doron kasa kuma an kirkireshi ta hanyar wadannan halayen nukiliya. Wannan galibi ana samun shi a cikin hayakin sarrafa makaman nukiliya, na haɗari ko mai sarrafawa.
Wannan binciken shine farkon wanda aka nuna uranium-236 bayanai a cikin Tekun Bahar Rum kuma farkon wanda aka samu tare da tsarin CNA's 1 MV AMS. Abin da binciken ya tattara a ƙarshe shi ne cewa a cikin wannan yankin akwai ƙarin hanyoyin isotope kuma a cikin su, hayaƙin da ake sarrafawa daga tashar sarrafa makamashin nukiliyar Marcoule a Faransa na iya zama sanadin; hatsarin Chernobyl; ko daga ayyukan da aka samo daga tsire-tsire na nukiliya waɗanda ke cikin tekun Bahar Rum.
Duk yadda suke bukata karin karatu don gano asalin uranium-236 da yawa.
