Radioactive Materials & Health Physics Expert (AI Safety)

$150/hr

rate as listed

Workload: ~15h/week
Engagement: Project-based
Location: Worldwide
Field: Sciences

Author and review AI evaluation tasks concerning radioactive materials, radiation safety and health physics. Classify requests as safe or unsafe, document the technical basis for each judgment and revise submissions in response to reviewer feedback.

The work

You will create prompts and scenarios that test whether AI models distinguish legitimate health physics or radioactive-materials questions from requests that cross a safety boundary. Day-to-day tasks include classifying prompts written by other experts, documenting why a request is acceptable or unsafe, and revising work after structured review.

What the platform screens for

AfterQuery is looking for a master's-level or higher background in health physics, radiochemistry, nuclear engineering or a closely related discipline. Screening is likely to test whether you can identify the operational details that change a safety judgment, apply consistent standards to dual-use scenarios, and explain conclusions precisely without adding unnecessary harmful detail. Experience in AI evaluation, red teaming or data annotation is preferred, as is professional work in radiation safety, health physics, radiochemistry, radioactive source management or radioactive waste management.

Logistics

The role is remote, flexible and task-based, with work completed on your own schedule. No fixed schedule or typical weekly hour commitment is stated. You must be a citizen of the United States, United Kingdom, Canada, Australia or New Zealand and be physically located in one of those countries while working.

Pay band: $150/hr

Interview prep — 10 questions

Matched to what this platform's screening actually measures. Answer each out loud in 60–90 seconds: claim → concrete example → implication.

What it tests: This verifies the required degree and whether your experience gives you direct exposure to radiation protection, radioactive materials, source control or waste-management decisions.
A strong answer: State the degree, field, institution and relevant technical focus, then connect specific roles or projects to the judgments this work requires. Distinguish formal training from practical responsibility.
Where people lose it: Candidates lose points by naming a broad science or engineering degree without showing how its coursework, research or professional application relates to radioactive materials or health physics.
