Try using new RadioButtonState(boolean, string) in your formbuilder.

ex.

Template:

    
DisOrDat
    
              
    
Choose
    

        

            
                Dis                                   
            
            
                Dat
            
        
    
    

Component

// create the form as a colleciton of Controls
this.form = formBuilder.group({
    disOrDat: formBuilder.group(
        {
            dis: [new RadioButtonState(true, 'dis')],
            dat: [new RadioButtonState(false, 'dat')]
        }, 
        { 
            validator: this.disOrDatValidator 
        }
    )
});

disOrDatValidator(group: ControlGroup) { 
    /* tslint:disable:no-string-literal */
    if (group.controls['dis'].value !== group.controls['dat'].value) {
    /* tsslint:enable:no-string-literal */    
        return false;
    }

    // return null means validation passed
    return null;
}  

doIt() {
    // handle form submit
}
