BackgroundBackgroundBackgroundBackground
A lot of studies for 30 years by many groups- Fabrication of detector material (PADC) sensitivity, transparency, stability, etc.- Sensitization by radiator for higher energies- Automatic counting system
“Personal neutron dosimetry with PNTD”
Practical application (at commercial base)- 30,000 pieces per month (fast processing)- stability, accuracy, fast processing
Present status of CTC servicePresent status of CTC servicePresent status of CTC servicePresent status of CTC service
- PADC fabrication in own laboratory quality control of detector material- Reduction of false pits by pre-soaking- Fast imaging system by HSP-1000

Purpose of this studyPurpose of this studyPurpose of this studyPurpose of this study
Check of existing techniques for improving sensitivity to 15-MeV neutrons without any modification in detector material & etching conditions
1. Analysis of other parameters (1-a) distribution in etch-pit diameter (1-b) distribution in gray size (1-c) distribution in shape factor
