Na'urar auna zafin jiki ta lantarki ( EPD )

Na'urar auna zafin jiki ta lantarki ( EPD ) na'urar auna zafin jiki ta lantarki ce ta zamani don kimanta yawan hasken ionizing da mutum ke amfani da shi don kare radiation . Na'urar auna zafin jiki ta lantarki tana da fa'idodi fiye da tsofaffin nau'ikan cewa tana da ayyuka masu inganci da yawa, kamar sa ido akai-akai wanda ke ba da damar gargaɗin faɗakarwa a matakan da aka saita da kuma karanta adadin da aka tara kai tsaye. Ana iya sake saita shi zuwa sifili bayan amfani, kuma yawancin samfuran suna ba da damar sadarwa ta lantarki ta kusa da filin don karantawa da sake saitawa ta atomatik. 
Yawanci ana sanya su a wajen tufafi, kamar a ƙirji ko jiki don wakiltar yawan da jiki ke buƙata. Wannan wurin yana lura da fallasa ga mafi yawan muhimman gabobin jiki kuma yana wakiltar yawan nauyin jiki.

Waɗannan suna da amfani musamman a wuraren da ake yawan shan magani inda lokacin zama na mai shan maganin ya takaita saboda ƙarancin shan magani.

 Na'urar auna PIN 
Ana amfani da diodes na PIN don auna yawan radiation da ake buƙata don aikace-aikacen sojoji da ma'aikata.

 Na'urorin auna MOSFET 
Ana amfani da na'urorin auna zafin jiki na MOSFET  yanzu a matsayin na'urorin auna zafin jiki na asibiti don hasken radiation na radiotherapy. Babban fa'idodin na'urorin MOSFET sune:

1. Na'urar auna MOSFET tana karanta kai tsaye tare da yanki mai siriri sosai (kasa da 2 μm).

2. Girman MOSFET na zahiri idan an naɗe shi bai wuce 4 ba mm.

3. Siginar bayan an yi amfani da ita za ta kasance a ajiye ta har abada kuma ba ta dogara da adadin da aka ɗauka ba.

Oxide na ƙofar MOSFETs, wanda aka saba amfani da shi azaman silicon dioxide, abu ne mai aiki a cikin dosimeters na MOSFET. Radiation yana haifar da lahani (wanda ke aiki kamar nau'ikan ramin electron) a cikin oxide, wanda hakan ke shafar ƙarfin wutar lantarki na MOSFET. Wannan canjin ƙarfin wutar lantarki yana daidai da adadin radiation. Ana kuma gabatar da madadin dielectrics na ƙofar high-k kamar hafnium oxide, hafnium dioxide  da aluminum oxides a matsayin masu auna radiation.
