Radioactive Materials & Health Physics Expert (AI Safety)

Usually 2 to 3 weeks at 10 to 20 hours a week. AfterQuery re-hires specialists for new projects when AI labs need their field, so plan for it as short, well-paid contracts.

It depends on the contract, usually 15 to 30 days after you send your invoice. Check the terms in your contract, and ask your project contact if the timing matters to you.

Tasks are slow and careful. One task can take 45 to 60 minutes of checking citations or calculations, and you're judged on quality more than speed.

It's closer to teaching. You grade the AI's logic, correct its mistakes and write the expert reasoning it lacks, instead of producing work for a client.

You check AI answers to STEM questions, correct their errors and write expert reasoning. As a Radioactive Materials & Health Physics Expert (AI Safety), you're hired for that judgment, so hands-on STEM experience matters.

This role lists a master's degree. The domain assessment usually matters more, and if you pass it the degree is often secondary. Some platforms check credentials, so list your qualifications accurately.

This role is open only to people based in Australia, Canada, New Zealand, the United Kingdom, and the United States. The limit is usually about where the platform can legally hire, so applying from elsewhere rarely leads to an offer. Check the description for tax or right-to-work rules before you apply, since they can differ by country.
