Article Synopsis
- - A study measured natural and artificial radionuclides in baby foods sold in Italy using various techniques like liquid scintillation and mass spectrometry.
- - The measured activity concentrations for radionuclides such as Po, U, Th, and K fell within specific ranges, while levels for Cs and Ra were below detection limits.
- - The calculated annual effective dose from these radionuclides for a one-year-old infant is considered safe and well below international safety standards, indicating minimal radiological risk from these baby foods.
Article Synopsis
- The Global Health Security Initiative (GHSI) created a lab network to improve response capabilities in case of a radiological emergency, focusing on radionuclide bioassays.
- 18 laboratories participated in a test with a urine sample containing high-risk radionuclides to assess their ability to analyze and report results within 72 hours.
- While all labs detected some radionuclides, many faced challenges in testing multiple radionuclides simultaneously and reporting consistent results, highlighting the need for improved collaboration and capacity building among the labs for emergency situations.
GHSI EMERGENCY RADIONUCLIDE BIOASSAY LABORATORY NETWORK: SUMMARY OF A RECENT EXERCISE.
Radiat Prot Dosimetry
November 2016
Article Synopsis
- The Global Health Security Initiative (GHSI) set up a lab network to improve their response to radiological or nuclear emergencies, focusing on radionuclide bioassay capabilities.
- A recent exercise tested labs on their ability to screen biological samples for radionuclide contamination, specifically using urine samples spiked with Americium (Am), and evaluate their medical intervention strategies.
- While labs demonstrated proficiency in rapid screening and dose assessment, gaps were identified, prompting the need for standardized practices and potential future exercises involving more international labs.
Nine laboratories participated in an intercomparison exercise organised by the European Radiation Dosimetry Group (EURADOS) for emergency radiobioassay involving four high-risk radionuclides ((239)Pu, (241)Am, (90)Sr and (226)Ra). Diverse methods of analysis were used by the participating laboratories for the in vitro determination of each of the four radionuclides in urine samples. Almost all the methods used are sensitive enough to meet the requirements for emergency radiobioassay derived for this project in reference to the Clinical Decision Guide introduced by the NCRP.

The untoward effects of (131)I have been mainly studied in male patients treated with high doses for thyroid cancer. In the present work we studied the absorbed radiation dose to the testes and testicular function in hyperthyroid men after (131)I treatment.

WBCs require adequate calibration procedures that rely on the use of suitable calibration phantoms. A previous study carried out at the ENEA-Radiation Protection Institute was aimed at designing a head calibration phantom in which a heterogeneous distribution of 241Am point sources could satisfactorily approximate an assumed homogeneous contamination throughout the head bones.
