On 17 November 1992 Thiệp was employed as the director of the Vietnam National Centre for Scientific Research in Hanoi. During a routine task, he placed his hands into a particle accelerator to adjust a sample of gold ore. This adjustment would usually be done using compressed air, but Thiệp entered the room and adjusted the samples by hand.
He is known for surviving a radiation accident in 1978, when a high-energy proton beam from a particle accelerator passed through his head. [ 1 ] [ 2 ] Accident
It is known to be responsible for six accidents between 1985 and 1987, in which patients were given massive overdoses of radiation, which were in some cases on the order of hundreds of grays. Three patients died as a result of the overdoses. These accidents highlighted the dangers of inadequate software control of safety-critical systems.
A massive project to build one of the world’s most powerful particle accelerators at Fermilab has been halted since May 25 while federal authorities investigate an accident that severely injured ...
The Tevatron (background circle), a synchrotron collider type particle accelerator at Fermi National Accelerator Laboratory (Fermilab), Batavia, Illinois, USA. Shut down in 2011, until 2007 it was the most powerful particle accelerator in the world, accelerating protons to an energy of over 1 TeV (tera electron volts). Beams of protons and ...
A simulated particle collision in the LHC. The safety of high energy particle collisions was a topic of widespread discussion and topical interest during the time when the Relativistic Heavy Ion Collider (RHIC) and later the Large Hadron Collider (LHC)—currently the world's largest and most powerful particle accelerator—were being constructed and commissioned.
The 2022 Honda’s crash mitigation system kicked in at the point of impact, helping ease the collision, Gruver said. The Honda was going about 50 mph when it struck the trooper’s vehicle.
The 1990 Clinic of Zaragoza radiotherapy accident was a radiological accident that occurred from 10 to 20 December 1990, at University Clinic Hospital Lozano Blesa of Zaragoza, in Aragon, Spain. In the accident, at least 27 patients were injured , and 11 of them died due to the overexposure, according to the International Atomic Energy Agency ...
