Hasil pengukuran laju paparan radiasi pada kaca yang digunakan sebagai
proteksi radiasi pada keenam titik pengukuran dengan menggunakan surveymeter
adalah 0,6 mR/jam, dibandingkan dengan NBD untuk radiografer (2,5 mR/jam) maka
nilai laju paparan radiasi pada ruang operator dinyatakan aman.
Kata kunci: paparan radiasi, kaca Pb, ruang operator
