ALOKA Co., Ltd. is a specialized manufacturer of radiation measuring devices. Its history of in-house development began with the DC-1 GM tube measuring device in 1954. ALOKA provides high-quality products and services under an integrated system covering development, production, sales, and maintenance, and contributes to the effective use of radiation in energy, medicine, research, and industry.
Design, manufacture, sale, and maintenance of radiation measuring devices.
Radiation monitoring systems for medical or laboratory use, environmental radiation monitoring systems, survey meters, electronic pocket dosimeters, alpha-beta counting systems, liquid scintillation systems, automatic gamma counters, and radioisotope dose calibrators.
ALOKA survey meters support contamination checks and dose-rate surveys in nuclear facilities: alpha/beta surface contamination meters, gamma and X-ray dose-rate meters, and neutron meters covering thermal neutrons to about 15 MeV.

ALOKA liquid scintillation systems measure low-energy beta emitters such as ³H and ¹⁴C for nuclear and environmental monitoring. LSC-8000 and high-performance LSC-LB8 deliver reliable, ultra-low-background measurement with a unique detector design.

ALOKA active pocket dosimeters provide on-the-spot personal dose monitoring for radiation workers. PDM-701, PDM-702 and PDM-707 cover gamma/X-ray applications; ALOKA’s broader lineup also includes neutron dosimetry.
