Removal of radioactive iodine and cesium in water purification processes after an explosion at a nuclear power plant due to the Great East Japan Earthquake.

The presence of radionuclides at five water purification plants was investigated after an explosion at a nuclear power plant hit by the Great East Japan Earthquake on 11 March 2011. Radioactive iodine (¹³¹I) and cesium (¹³⁴Cs and ¹³⁷Cs) were detected in raw water in Fukushima and neighboring prefectures. ¹³¹I was not removed by coagulation-flocculation-sedimentation.

[Clinical features of transurethral anterior sphincterotomy and urological management of patients with cervical spinal cord injury].

Background: The ideal urological management for the patients with cervical spinal cord injury (CSCI) is to obtain catheter free urination and to prevent urinary tract complications. We have evaluated cases that had undergone transurethral anterior sphincterotomy from the view-point of the operative indications and the efficacy.

Methods: We carried out sphincterotomy 166 times on 133 male patients with CSCI in our Center.
