Radioactivity of long-lived gamma emitters in egg

DOI: 10.48129/kjs.11911

Abstract

Radioactivity in egg was investigated. The targeted radionuclides were the long-lived gamma emitters ²²⁸Ra, ²²⁶Ra, and ⁴⁰K. Measurements were carried out using a high purity germanium detector. The calculated annual effective dose due to egg consumption was 79 μSv yr^-1, which forms 1/4 of the 290 μSv yr^-1 world average ingestion exposure from natural sources. Hence, no radiological hazards exist from egg consumption due to the presence of the investigated radionuclides.
