Xa kuthelekiswa namanye amatye endalo, amatye entaba-mlilo aneempawu ezibalaseleyo. Ukongeza kwiimpawu eziqhelekileyo zamatye aqhelekileyo, nawo anesitayile sawo esahlukileyo kunye nemisebenzi ekhethekileyo. Thatha umzekelo we-basalt. Xa kuthelekiswa ne-marble kunye namanye amatye, ilitye le-basalt line-radioactivity ephantsi, ngoko ke lingasetyenziswa ngokukhuselekileyo kwiindawo zokuhlala zabantu, kwaye aliyi kwenza abathengi abakhetha amatye okuhombisa ngaphakathi bangaziqhelanisi. Ilitye lentaba-mlilo liqinile kwaye lingasetyenziselwa ukuvelisa ipleyiti yelitye ebhityileyo kakhulu. Emva kokusila kakuhle komphezulu, ukukhanya kunokufikelela kwiidigri ezingama-85, umbala ukhanya kwaye ucocekile, kwaye inkangeleko intle kwaye intle. Isetyenziswa kakhulu kuzo zonke iintlobo zokuhombisa udonga lwangaphandle lwesakhiwo, isikwere sendlela kamasipala kunye nepavement yomgangatho weendawo zokuhlala. Ikwalilitye elithandwayo kuzo zonke iintlobo zezakhiwo zakudala, izakhiwo zaseYurophu kunye nezakhiwo zegadi. Lithandwa kakhulu kwaye lamkelwe ngabathengi ekhaya nakwamanye amazwe. Izinto zelitye lentaba-mlilo ziyamelana nemozulu, imozulu kunye nokuqina; ukufunxwa kwesandi kunye nokunciphisa ingxolo kuyanceda ekuphuculeni imeko yokuva; kulula kwaye kwendalo, ukuphepha ukukhanya kuyanceda ekuphuculeni imeko yokubona; Ukufunxwa kwamanzi, ukungatyibiliki kunye nokumelana nobushushu kuyanceda ekuphuculeni imeko-bume ye-somatosensory; umsebenzi "wokuphefumla" okhethekileyo unokulungisa ukufuma komoya kwaye uphucule imeko-bume yendalo. Zonke iintlobo zeenzuzo ezikhethekileyo zinokuhlangabezana nefashoni entsha yabantu kweli xesha lanamhlanje ekufuneni ukhuseleko olulula nolwendalo, olukhuthaza ukukhuselwa okuluhlaza kunye nokusingqongileyo. Isixhobo sombhobho wamatye okwenziwa ngentaba-mlilo.
