Amchitka Island Environmental Analysis at Idaho National Laboratory
The Idaho National Laboratory (INL) provided support to Consortium for Risk
Evaluation with Stakeholder Participation (CRESP) in their activities which is supported
by the Department of Energy (DOE) to assess the impact of past nuclear testing at
Amchitka Island on the ecosystem of the island and surrounding ocean. INL participated
in this project in three phases, Phase 1, Phase 2 and Phase 3.
The roles of the INL in phase 1 A were to provide a method manual which explains the
methods and measurement procedures to analyze alpha, beta, and gamma emitting
radioisotopes in the environmental samples collected at Amchitka Island, a quality
assurance plan that details how samples will be handled, data reporting requirements,
calibrations, blank analysis, and setup of a performance demonstration program using
In Phase I B, a common set of measurement methods and quality assurance plan were
identified. In order to validate the methods identified with the identified sample matrices,
INL did some method development work. Under this task, INL purchased samples
similar to Amchitka samples from the local stores. These samples included fish (like
salmon and halibut), crab, lobsters etc. The INL also purchased some kelp to test the
methods. Samples were divided into three categories. (a) Flesh or tissue samples, (b)
bone, and (c) kelp. All samples were ground to smaller pieces to make them
homogeneous. The analytical scheme for each type of samples is shown in the following
