Detailed Description of Services : Isse Lab, LLC

Isse Lab, LLC provides specialized consulting in radiation measurement, regulatory compliance, and medical isotope technologies, combining academic expertise with practical experience in regulatory administration and industrial measurement systems.
Based on the representative's professional background and experience, we provide services in the following areas. After consultation regarding the scope of work and budget, and upon mutual agreement, we proceed with either a technical advisory contract or the issuance of a formal quotation and service agreement as appropriate.
The representative's academic publications are available here (researchmap in English).

The field of radiation in Japan has certain distinctive characteristics compared to other countries. These differences arise from variations in regulatory frameworks as well as from differences in public perception of radiation risk. In Japan, due to historical factors, radiation regulations and public attitudes toward radiation risk tend to be stricter than in many other countries.
We provide support to international companies seeking to enter or expand in the Japanese market in radiation-related fields.
