“…[1][2][3] In situ gamma spectrometry can quantify average inventories over a large area around the point of measurement, resulting in less statistical uctuation of the obtained data than that obtained by soil-sampling-based evaluations. [4][5][6][7][8][9] Intercomparison is useful for verifying the reliability, accuracy, and consistency of measurements among the participants. In case of intercomparison of sample measurements among different laboratories, a common reference material can be measured at each laboratory.…”

Intercomparison of in situ gamma spectrometry was organized at a site contaminated by the radioactive fallout that originated from the Fukushima Dai-ichi Nuclear Power Plant accident. This intercomparison was conducted by eight teams from four different institutions, which have contributed to the government-led project to construct distribution maps of radionuclides deposited on the ground soil. The resultant 134 Cs and 137 Cs inventories evaluated by the participants agreed within 6% of the 40 K inventories distribution maps of the radionuclide inventory in the ground soil.

“…The advantages of this method involve obtaining prompt available results about the average activity of radionuclides over large area [3]. On the contrary, the main disadvantage of the method is that the accuracy and the precision of the analysis results strongly depend on the radionuclide depth distribution within the soil [4,5].…”

In this work, the influences of the soil densities and the radionuclide depth distributions(RDD) on the Full Energy Peak Efficiency (FEPE) calculation of the in-situ gamma rayspectrometer using the In Situ Object Counting Systems (ISOCS) software were studied. The data of the RDDs at the sites were investigated by using laboratory HPGe gamma spectrometer. Six different RDDs of 40K, 226Ra and 232Th were found at four studied sites with radionuclide deposition moving from surface to deeper positions. The results show that FEPE values vary strongly for the different RDDs, especially for the low gamma ray energies. Use of the uniform model for calculating FEPEs can result in noticeable errors from 29% to 101% for the realistic RDD of the exponential form (surfaceradionuclide deposition), negative variations from 14% to 30% for the realistic RDD of having a radionuclide deposition at the 30 cm depth, and negligible variations of less than 5 % for the realistic RDD of quasi uniform form in the range of gamma ray energies of interest.

In essence, this technique involves the collection of gamma spectra using a fieldportable detector mounted on a tripod above the ground and subsequent analysis of the spectra to determine the activity of specific radionuclides contained within the soil.…”
