Radioactive substances have been used in medicine for over 100 years. Today, medical use of radiation is the largest, and a growing, manmade source of radiation exposure. Nuclear medicine has become an important diagnostic and therapeutic specialty, and there are nearly 100 different procedures that provide information about virtually every major organ system in the body. The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) estimated that, worldwide, more than 30… Expand

Radiation Protection for Patients
TLDR
This chapter presents important considerations for radiation protection of the nuclear medicine patient with constant vigilance on overall safety. Expand
Radiological Justification for and Optimization of Nuclear Medicine Practices in Korea
  • B. Kim
  • Medicine
  • Journal of Korean medical science
  • 2016
TLDR
The development of patient-radiation-dose monitoring software, and a national registry and management system of patients and radiopharmaceuticals must take into account the medical reality of Korea, in order to implement reasonable radiological justification and optimization. Expand
Beta radiation exposure of staff during and after therapies with 90Y-labelled substances.
TLDR
Measurements of the dose rate around patients, made using survey meters with sufficient response to beta particles, indicate that the exposure of caregivers and family members is considerably higher than previously assumed, and was dominated by primary beta radiation instead of bremsstrahlung. Expand
Patient doses from fluoroscopically guided cardiac procedures in pediatrics.
TLDR
A set of patient dose values, in terms ofAir kerma area product (KAP) and entrance surface air kerma (ESAK) measured in a pediatric cardiac catheterization laboratory equipped with a biplane x-ray system with dynamic flat panel detectors are presented. Expand
A Case Study about Counting Uncertainty of Radioactive Iodine ( 131 I) in Public Waters by Using Gamma Spectrometry
The radioactive iodine (I) presents in the environment through the excrete process of nuclear medicine patients. In the detecting of low level of I in the public water, the counting uncertainty hasExpand
RADIATION PROTECTION IN THE RELEASE OF PATIENTS RECEIVING 131I TREATMENT.
TLDR
The estimated release times from the confinement were well with the radiation safety criteria, whereas instruction are given concerning precaution times to limit radiation exposure to family members and co-worker. Expand
How Radiation Protection Influences Quality in Radiology
TLDR
It is concluded that RP and radiation management are integral elements for quality in imaging and intervention and leadership and on-going collaboration by developing and implementing innovative actions will ensure RP and quality objectives are attained in the not too distant future. Expand
Paediatric entrance doses from exposure index in computed radiography.
TLDR
Typical mean thicknesses for several age bands of paediatric patients was estimated to calculate ESAK from the EL values, using results of experimental measurements with phantoms for the typical x-ray beam qualities used in paediatric examinations. Expand
Measurements and applications of dose indices in radiography
Abstract Assessments of radiation dose and image quality are required in diagnostic radiography for quality assurance and optimization studies. In work currently being undertaken, dose indices wereExpand
Development of Diagnostic Reference Levels Using a Real-Time Radiation Dose Monitoring System at a Cardiovascular Center in Korea
TLDR
The construction of a radiation dose monitoring system based on digital imaging and communications in medicine (DICOM) data and its use at the cardiovascular centre of the University Hospitals in Korea represents the first of its kind in Korea. Expand

Radiological protection guidance for radioactive patients — new data for therapeutic 131 I
TLDR
Thyroidal retention data can be used to determine body radioactivity at any interval after the administration of 131 I for treatment of thyrotoxicosis, thus obviating the need for serial measurements in every individual patient. Expand
Definitive improvement in the approach to the treated patient as a radioactive source.
  • E. Lubin
  • Medicine
  • Journal of nuclear medicine : official publication, Society of Nuclear Medicine
  • 2002
TLDR
Field measurements of the family members of patients treated on an outpatient basis proved to be below calculated exposures following the precise oral and written instructions that they received, basis of those measurements to facilitate the decision of releasability and the duration of contact restriction specific for the different members of the patient’s human environment. Expand
Iodine-131 contamination from thyroid cancer patients.
TLDR
The relatively high activities present in the saliva, urine and on the skin of these patients emphasizes the need for all individuals coming in contact with these patients to be made aware of the contamination hazard present. Expand
Calculating the absorbed dose from radioactive patients: the line-source versus point-source model.
TLDR
The line- source model is a more realistic and practical approach than the traditional point-source model for determining the dose to individuals exposed to radioactive patients with widespread activity distributions. Expand
Radiation dose rates from adult patients receiving 131I therapy for thyrotoxicosis
TLDR
The periods to restrict close contact with young children in order to limit their dose to 1 mSv were very similar to the current recommendations based on retained activity. Expand
Radiation safety considerations for post-iodine-131 hyperthyroid therapy.

  • Medicine
  • Journal of nuclear medicine : official publication, Society of Nuclear Medicine
  • 1991
TLDR
New guidelines based on patient measurements as to when iodine-131- (131I) treated hyperthyroid patients may resume close personal contact are developed based on the administered dose that are rational and in conformity with existing radiologic health standards. Expand
Radiation dose rates from patients receiving iodine-131 therapy for carcinoma of the thyroid
TLDR
Sensible guidelines can be derived to limit the dose received by members of the public and staff who may come into contact with cancer patient treated with radioiodine to less than 1 mSv. Expand
Contamination of the home environment by patients treated with Iodine-131: initial results.
TLDR
The twin sodium iodide radiation detectors employed to analyze iodine-131 transfer from thyroid patients to their families are able to detect as little as 92 pCi of iodine 131 in adult thyroids and could possibly double the risk of thyroid malignancy in children over what is expected normally. Expand
Radioactive waste discharge quantities for patients undergoing radioactive iodine therapy for thyroid carcinoma
TLDR
The discharge of activity for 174 patients undergoing treatment of thyroid carcinoma with radioactive iodine is reported, finding that approximately 55% of administered activity is excreted in the first 24 h and that 85% ofadministered activity is discharged to the sewer over a typical inpatient stay of 5 days.

[Monitoring of 131I incorporation in nuclear medicine personnel by self accomplished measurements].
TLDR
A surveillance with the employees measuring themselves similarly to the autonomous contamination survey using hand-foot-clothing monitors is presented as an alternative to the monitoring according to the official guidelines to allow a more reliable and more precise dosimetry. Expand
