BIODOSIMETRY AND BIODOSIMETRY NETWORKS FOR MANAGING RADIATION EMERGENCY.

Biological dosimetry enables individual dose reconstruction in the case of unclear or inconsistent radiation exposure situations, especially when a direct measurement of ionizing radiation is not or is no longer possible. To be prepared for large-scale radiological incidents, networking between well-trained laboratories has been identified as a useful approach for provision of the fast and trustworthy dose assessments needed in such circumstances. To this end, various biodosimetry laboratories worldwide hav...


CONCEPTS OF OPERATIONS FOR A US DOSIMETRY AND BIODOSIMETRY NETWORK.

The USA must be prepared to provide a prompt, coordinated and integrated response for radiation dose and injury assessment for suspected radiation exposure, whether it involves isolated cases or mass casualties. Dose estimation for radiation accidents typically necessitates a multiple parameter diagnostics approach that includes clinical, biological and physical dosimetry to provide an early-phase radiation dose. A US Individual Dosimetry and Biodosimetry Network (US-IDBN) will increase surge capacity for c...

Radiation-Induced Phosphorylation of Serine 360 of SMC1 in Human Peripheral Blood Mononuclear Cells.

In the event of a mass casualty radiation scenario, biodosimetry has the potential to quantify individual exposures for triaging and providing dose-appropriate medical intervention. Structural maintenance of chromosomes 1 (SMC1) is phosphorylated in response to ionizing radiation. The goal of this study was to develop a new biodosimetry method using SMC1 phosphorylation as a measure of exposure to radiation. In the initial experiments, two normal human cell lines (WI-38VA-13 and HaCaT) and four lymphoblasto...

Development of electronic training and telescoring tools to increase the surge capacity of dicentric chromosome scorers for radiological/nuclear mass casualty incidents.

Dicentric chromosome assay (DCA) is most frequently used for estimating the absorbed radiation dose in the peripheral blood lymphocytes of humans after occupational or incidental radiation exposure. DCA is considered to be the "gold standard" for estimating the absorbed radiation dose because the dicentric chromosome formation is fairly specific to ionizing radiation exposure and its baseline frequency is extremely low in non-exposed humans. However, performance of DCA for biodosimetry is labor intensive an...

Hematological Effects of Non-Homogenous Ionizing Radiation Exposure in a Non-Human Primate Model.

Detonation of a radiological or nuclear device in a major urban area will result in heterogenous radiation exposure, given to the significant shielding of the exposed population due to surrounding structures. Development of biodosimetry assays for triage and treatment requires knowledge of the radiation dose-volume effect for the bone marrow (BM). This proof-of-concept study was designed to quantify BM damage in the non-human primate (NHP) after exposure to one of four radiation patterns likely to occur in ...

NON-RADIOLOGICAL IMPACT OF A NUCLEAR EMERGENCY: PREPAREDNESS AND RESPONSE WITH THE FOCUS ON HEALTH.

Available experience from Chernobyl and Fukushima clearly demonstrate that nuclear emergencies may result in low and very low exposure levels, at which psychological and social effects among the affected population will dominate over the actual biological effects of ionising radiation. International protection standards and guidelines request, that both radiological and non-radiological health consequences have to be considered in preparedness and response to an actual emergency and there is a need to broad...

Predicting Appropriate Hospital Admission of Emergency Department Patients with Bronchiolitis: Secondary Analysis.

In children below the age of 2 years, bronchiolitis is the most common reason for hospitalization. Each year in the United States, bronchiolitis causes 287,000 emergency department visits, 32%-40% of which result in hospitalization. Due to a lack of evidence and objective criteria for managing bronchiolitis, clinicians often make emergency department disposition decisions on hospitalization or discharge to home subjectively, leading to large practice variation. Our recent study provided the first operationa...

Mapping radiation distribution on ground based on the measurement using an unmanned aerial vehicle.

Mapping the radiation distribution on ground during a radiological emergency monitoring, or decontamination mission is an important task. Accurate knowledge of the radioactivity distribution can help radiation workers locate the contamination, which reduces unnecessary radiation exposure to personnel and perhaps to some extent also the exposure to the public. Recently, radiation monitoring systems based on unmanned aerial vehicles (UAV) have been widely studied and employed. However, development of algorith...

Spatial-temporal modeling of background radiation using mobile sensor networks.

Modeling of background radiation for the urban environment plays an important role in homeland security. However, background radiation is difficult to assess due to its spatial-temporal fluctuations caused by the variation in soil composition, building materials, and weather patterns etc. To address the challenge of background radiation modeling, we developed a mobile sensor network to continuously monitor the background radiation; we also proposed a maximum likelihood estimation algorithm to decouple and e...

Mebendazole potentiates radiation therapy in triple-negative breast cancer.

The lack of a molecular target in triple negative breast cancer (TNBC) makes it one of the most challenging breast cancers to treat. Radiation therapy (RT) is an important treatment modality for managing breast cancer, however we previously showed that RT can also reprogram a fraction of the surviving BC cells into BC initiating cells (BCICs), that are thought to contribute to disease recurrence. In this study we characterize mebendazole as a drug with potential for preventing radiation-induced reprogrammin...
