The neutron bomb woulal be morecostly to nxanufacture than vou]d a 10 kt, ffeapon of tbe ssne rattiation ra,nge and.greater blast action. Both nini-nukes and neutron bombs can be seen asexpressions of an effort to nake nuclear veapons less d.estructive to the surround.ings if they were to be used in actual warfare anil thus, according totheir proponents, ns,ke nuclear deterrence at the tactical Level rnore credible. 82, Pl-ans by the united states to p"oduce the neutron weapon anal to introduce itin Europe have been halted fo? the ti.ne being. The !'rench Government hasreeently e.nnounced that France has d.eveloped and tested neutron bombs, anal thatdecisions on production and deploym.ent vi1l be taken in the years to cone. TheSoviet Leadership has stateal that the Soviet Union has developed and tested. a neutron bondb but decided. not to deploy it at present. 83. Another type of trtailoxed -effects t' weapon discussecl in the United States isthe rrreduced resid-ua1-ratliation'r (RlR) or "minirnun residual-raillation" (rrnn) lteapon. Like the In veapon, this vould. derive a substaDtial part of its energl fronr fUsion, but the weapon casing would be d.esigned so as to reduce tbe out f]-uxof neutrons. Such weapons, rrhich coul-d. probably have a significantly largeryielal than the proposed ER werhead.s, coutd. be useil in surface or subsurfacebursts, for insts;rce to create huge craters with a signifi.cantly smal-ler smountof radioactive fa-llout than an ordinary fission rrarheaal. 84. There has been a great dea]. of both specu-lation and. serious research regard.ing the possibility of building a thernonuclear explosive vithout a fission explosion as initiator" fn particu-lar, the use of lasers to initiate fusionreactions has been stuatieat. Hovever, there appeaJas to be no proEpect for success along these lines, in anything that nigbt be used. as a aleliverable nuclear lreapon. 85. Despite the research anal d evelopment going on in the fiel-d of special typesof warheads, no naJor breakthrough is ]-ikeLy to occur with f,egard to the basic
analysis: The text appears to be discussing advanced nuclear weapons technology, including neutron bombs and reduced-residual-radiation (RIR) weapons. The language used is technical and focuses on the characteristics and potential uses of these weapons, rather than their broader societal impact. This suggests that the category should be focused on science and technology.
