                               quick deterioration Of Material so treated.       As an example, the
                               deslructi on of bacl er i a I spores requires 20 to 30 seconds exposure
                               at 400* C.

                           b . Liquid disinfectants.     These are mostly solutions of bactericidal
                               and fungicidal substances; a great variety of such disinfectants
                               may be of value, the choice in each case depending upon the
                               Situation.    Examples of Disinfectants are glucaraldehyde, a
                               propiolactone, potassium permanganale (of limited application ow@ng
                               to its high speed of reduction), chlorinated lime, formaldehyde,
                               sodium hydroxide or potash, washing soda, and copper sulfate.

                                    Chlorinated derivatives are represented by sodium hypochlorile
                               and chloramine.    Iodine derivatives include iodine alcoholic
                               solutions and iodophores (e.g. iodized polyvinyl pyrolidone) where
                               iodine, combined with an organic aze7@, is slowly released Lhroueh
                               simple dilution in Water.     'hese @aicai:n derivatives act in a few
                               seconds or minutes, depending on the concentration used, and owing
                               Lo their very high oxidising power.

                                    Phenots and their derivatives (cresol i    'n the form of sodic
                               creSylOt, LhyMOI, halogenous phenols, hexachlorophene) are in
                               general not easily soluble in water and have little action on
um compounds are mainly
                               bactericidal.

                                    All those substances could however be less efficient than
                               anticipated if the environment where they are introduced, or if the
                               Coating on which they are sprayed, contains or supports natural
                               products known as antagonists (organic compounds, faLS,
                               EhiosulfaLe, ferrous salts).

                               C.   Gaseous DisinfectanEs.    A nlunber of substances are available,
                               the most efficient being ethylene oxide, formaldehyde, and
                               peracetic acid.    Sulfurous anhydride may be used for surface
                               disinfection, despite its raeh@r weak effect on spores.

                               d.   Disinfection by Filtration.     The main interest in filtration
                               procedures would be in connection with the sterilization of
                               drinking water.    Filtration units for delivering potable water are
                               in common military use. Against toxins they must be equipped With
                               an activated charcoal column.


                   POSSIBLE PRACTICAL APPLICATIONS

                   504.    It is highly questionable whether the decontamination of materiel,
                   equipment, or buildings is at present a realistic possibility. If it should,
                   however, be judged desirable, the best methods would in most cases be gaseous
                   disinfection with formaldehyde or ethylene oxide, and liquid disinfectant
                   spread with specially-designed equipment. Special precautions need to be
                   taken with the use of these disinfectants as they are highly toxic to humans
                   and can damage electronic components.
