Abstract

Suprafetele contaminate cu materiale radioactive pot fi decontaminat, conform inventiei, prin circularea unei solutii apoase a unor reactivi de decontaminare care contin agenti de decontaminare ai acizilor organici, de obicei acidul oxalic si acidul formic în contact cu acestea. Reactivul preferat contine atît acid citric cît si EDTA în plus fata de acidul oxalic si acidul formic. S-a stabilit ca eficienta reactivilor de decontaminare ai acizilor organici poate sa fie prelungita si sub radiatia de ionizare prin adaugarea acidului formic a carui concentratie se mentine constanta în solutii în timpul procesului de decontaminare.
