Lead tungstate (PbWO₄/PWO) o se tioata scintillation e masani ona faʻaaogaina i suʻesuʻega o le fisiki malosi faʻapea foʻi ma faʻataʻitaʻiga faʻafomaʻi e pei ole PET (positron emission tomography) ma le CT (computed tomography).O se tasi o mea taua o le PWO, e maualuga lona mamafa, lea e mafai ai e le PWO ona faʻafefe gamma ave sili atu le lelei nai lo isi tioata scintillation.I le isi itu, o le mea lea e maua ai le maualuga maualuga o faailoilo i le pisa ma sili atu le fofo o le suʻeina o le radiation.O tioata PWO e lauiloa foi mo a latou taimi vave tali, lea e talafeagai ai mo faiga faʻapipiʻi faʻamaumauga maualuga.

E mafai foi ona latou tetee atu i le faaleagaina o le radiation ma le mautu mo se taimi umi, ma avea ai i latou ma filifiliga maufaatuatuaina mo talosaga faigata o le siosiomaga.Ae ui i lea, o le maualalo o le malamalama o tioata PWO pe a faʻatusatusa i isi mea faʻafefeteina e faʻatapulaʻaina ai lo latou lagona i nisi o talosaga.O tioata e masani lava ona tupu aʻe e faʻaaoga ai le Czochralski metotia ma e mafai ona faʻapipiʻiina i ituaiga eseese e faʻatatau i le talosaga.O tioata scintillator PWO o lo'o i ai fa'afitauli nei e tatau ona maitauina: PWO e maualalo le malamalama.O i latou e fa'aautu le leitio ma fa'apea e le talia mo nisi fa'aoga.E a'afia i fa'aleagaina fa'avevela.Amata ile tui ile va ole 1 ma le 10 Grey (10² - 10³ rad).Ma toe faʻafoʻi i le taimi poʻo le faʻafefe.
