The 2011 Decay Data Evaluation Project (DDEP) evaluation for ¹⁴⁷Nd includes recommended absolute emission intensities for the two main gamma-rays at 91.105 (2) keV and 531.016 (22) keV of 0.284 (18) and 0.127 (9) respectively, i.e. with uncertainties of 6.3% and 7.1%. These large uncertainties stem from inconsistencies in the published data and are unfit for modern purposes, since the production of ¹⁴⁷Nd is used as an important neutron flux dosimeter.

The LNE-LNHB has undertaken new absolute gamma-ray emission intensity measurements. The results of these measurements will be presented, along with a full uncertainty budget, and their effect on the recommended data uncertainties will be discussed.

2011年衰减数据评估项目（DDEP）对¹⁴⁷ Nd的评估包括建议的两种主要伽马射线的绝对发射强度，分别为91.105（2）keV和531.016（22）keV，分别为0.284（18）和0.127（9），即不确定性分别为6.3％和7.1％。这些巨大的不确定性源于已发布数据的不一致，并且不适合现代用途，因为将¹⁴⁷ Nd的产量用作重要的中子通量剂量计。

LNE-LNHB进行了新的绝对伽马射线发射强度测量。将介绍这些测量的结果以及完整的不确定性预算，并将讨论它们对建议的数据不确定性的影响。
