Samsung Faces Probe After Two Chip Workers Exposed to Radiation

South Korea’s nuclear safety authorities are carrying out an on-site investigation after two employees at a Samsung Electronics Co. semiconductor plant were exposed to radiation.

The employees are showing abnormal symptoms on their fingers because of localized exposure, though their blood tests are normal, the Nuclear Safety and Security Commission said in a statement Wednesday. They have been hospitalized at the Korea Institute of Radiological & Medical Sciences and are being monitored for further tests.
