Discussion on application of control level of radioactive contamination on personnel′s body surface in a nuclear and radiological emergency / 中华放射医学与防护杂志

There are differences and inconsistencies to some degree in the radioactive contamination control level of personnel′s body surface availiable in many national standards, thus puzzling the users. Therefore, it is proposed to compare the applicable scope, conditions and differences between relevant national standards, and combine with similar clinical nuclear medicine standards of radiological protection content to presevent recommendations on the contamination control level that should be correctly applied in an event of nuclear and radiological emergency. Based on the discussion of similar standards, the contaminated personnel with α of 0.04-10 Bq/cm 2 and β of 0.4-100 Bq/cm 2 are advised to be treated in the institutions with higher than secondary medical insititution. Both α econtamination control levels less than 0.04 Bq/cm 2 and β levels less than 0.4 Bq/cm 2 could be achivable, if fully decontaminated.

Medical follow-up of exposed victims after the " 5.7" accident of radioactive source in Nanjing / 中华放射医学与防护杂志

Objective@#To explore the long-term effects of radiation injury and to provide scientific basis for the evaluation of the effects of ionizing radiation injury by carrying out medical follow-up of patients involved in the " 5.7" radiative source accident in Nanjing in 2014.@*Methods@#Through interviewing and investigating, we inquired about the new disease history of the exposed patients from rehabilitation treatment to medical follow-up peroid. Physical and laboratory examinations were carried out. According to relevant standards, physiological and biochemical indexes such as hematopoietic system, immune system, endocrine system, ophthalmology, circulatory system, digestive system, urinary system and bone mineral density were systematically evaluated, with the long-term effects being evaluated.@*Results@#The patient′s vital signs were good without new diseases. The indexes of hematopoietic system, immune system and endocrine system tended to be normal, the circulatory system, digestive system and urinary system showed degenerative changes, the ophthalmic examination showed visual acuity continue to decline, and bone mineral density examination indicated low bone mass.@*Conclusions@#Physiological and biochemical indicators of the patients gradually returned to normal without obvious symptoms of radiation damage. Further medical follow-up observation still needs to continue.

National System of Medical Assistance for Radiation Emergencies and Relevant Researches

Korea has advanced nuclear and radioisotope industry, and it is urgent to establish a national system to countermeasure the radiation accidents and preparedness for radiation emergency medical management. The Government opened the National Radiation Emergency Medical Center (NREMC) in the Korea Institute of Radiological and Medical Sciences (KIRAMS) in 2002, and the NREMC is setting up a radiation emergency medical preparedness and assistance network in nationwide. On April 30, 2003 the special law was proposed for the physical protection of nuclear facilities and emergency response against radiological accidents, which includes medical preparedness and management. Detailed guidelines for this law is being prepared by the Ministry of Science and Technology (MOST), and will be take effect in February 2004. Per this guideline, regional emergency medical centers will be appointed by the MOST, and the NREMC will operate this national system including education of the medical personnel.
