Low-Dose Radiation Effects Research Facility (LERF)
The Low-Dose Radiation Effects Research Facility (LERF) was established to study the biological effects of long-term low-dose rate irradiation on large population of mice.
This facility is designed to allow us to keep mice under specific pathogen free (SPF) conditions and continuous low-dose rate irradiation.
SPF Area
SPF Area comprising of the SPF animal rooms, the irradiation rooms and so forth is maintained at 23±2 ℃ with 50±10% humidity, +6mm Aq atmospheric pressure, and a light/dark cycle of 12 hours.
Irradiation rooms
The three irradiation rooms are equipped with sealed Cesium-137 γ-ray sources of 74 GBq, 3.7 GBq, and 0.185 GBq, which enable us to continuously irradiate a maximum of 1,080 SPF mice with γ-rays at the 3 dose rate (20, 1, 0.05 mGy/day).
