CLEA software version 1.04, is a computer version of the CLEA model. It replaces CLEA software version 1.03 beta, the evaluation version of this software (which
in turn replaced CLEA UK, the previous version of the software). It also contains additional approaches, which may be useful for site-specific risk assessment
that are not described within the CLEA report but are covered in some detail within the handbook that accompanies the software. The handbook also provides a
detailed user guide explaining how to operate all of the functions of the software.
