This is a shared use educational and research facility for conducting experiments using a unsealed radioactive isotope.
In radiation controlled area,
various radionuclide (3H, 14C, 32P, 33P, 51Cr and 125I, etc.)
and radiation measuring instrument can be use.
User Registration
Official members of the yamaguchi university
(faculty, staff, and graduate student) can use this institute.
Before entering radiation controlled area,
you need to attend lecture for the safe handling of radioactive materials.
New subscribers, please attend at once,
the lecture and medical check in April and May or October.
Also the person who registered to continue in the next academic year,
please attend the lecture once per academic year.
There are ionizing radiation medical examination every six months.
Since the questionnaire is distributed, please be sure to submit.
In radiation controlled area, we provide equipments for measurement and experiment for shered use. Use of equipment is basically free; Use of consumables will be charged.

型式 Model: Aloka LSC-7200
用途 Use: ベータ核種 beta nuclide
購入時期 Purchase date: 平成26年度(2014-12-00)
備考 Note: For this type of equipments, this is the latest model we have.
Description:
It is used to measure samples containing beta nuclides such as 3H, 14C.
When using this device,
it is necessary to prepare dedicated
reagents (scintillation cocktail) and test tubes (counting vials).
Racks for 20 mL vials and racks for mini vials are available.
The measurement results are printed on paper.
The measurement results can also be brought back to the USB memory as a CSV text file using the attached PC.
