Profile: Sierra Radiation Dosimetry Service, Inc. specializes in offering radiation monitoring services. We offer a wide range of dosimetry products. We provide radiation dosimetry monitoring service and accurate radiation dose assessments. We use NVLAP Accredited Panasonic UD-802A thermo luminescent dosimeter (TLD) personnel monitoring badge for the determination of occupational radiation dose for the employees. Our TLD dosimeter (X-ray badge) is designed for monitoring radiation exposure from X-ray, gamma, beta and neutrons of known energy. Our TLD badge measures radiation dose at three tissue depths which correspond to the deep, shallow, and lens of the eye doses required by 10 CFR 20. This dosimeter is nearly used for all medical and industrial radiation environments. Our TLD radiation dosimeter (dosimetery badge) is available for monthly, bi-monthly, or quarterly wear periods for routine personnel, area and environmental radiation monitoring. Our TLD dosimeter labels show the appropriate TLD wear-position on the body and are color coded to differentiate between radiation monitoring wear periods. Our radiation monitoring services are used in areas such as hospitals, medical clinics, university laboratories and nuclear & power plant facilities.
