The problem area of critical systems (CS) is considered. The termination of functioning of CS is inadmissible. Practice shows that for CS numerous and various problems are characteristic. For such systems the potential conflictness is characteristic, and the conflictness problem remains, in whole, unresolved. Thus, creation of means of maintenance of absence of conflict is necessary. The key problem of CS is allocated. It is a problem of information-system safety (ISS). The problem is formulated by A.V.Chechkin and includes traditional concept of information security. ISS has aspects of information stability and system safety. ISS can be provided on the basis of a special formalism of CS and construction on its basis of the intellectual modeling environment of CS. It proves necessity of working out of a method of intellectualization of CS - a method of maintenance of ISS of CS. As a basis of a formalism of CS the concept of the environment of radicals offered by A.V.Chechkin is chosen. Requirements to method of maintenance of ISS of CS are formulated. The formalism of schemes of radicals with which help construction of model of problem area of CS in the form of environment of radicals is carried out is offered. Construction of model of the environment of radicals on the basis of schemes of radicals is described. Syntax and semantics of the developed formalism are considered. Symbolical representation of schemes of radicals, and also their geometrical display and representation by means of tables (tables of databases) is considered. Use of tabular representations of schemes of radicals for the environment of radicals is considered also
