Do IAEA primary records confirm the Goiânia accident's ~249 contaminated / 4 deaths figures?

The question

claim-prussian-blue-was-deployed-at-scale-in-the-1987-goiania-cesium-137-accident cites, from a Tier-4 aggregator, that the 1987 Goiânia cesium-137 accident contaminated on the order of 249 people and killed four. These figures carry an [unverified-quant — needs primary] flag. Do the IAEA's primary records confirm the counts?

Why it matters

Quantitative claims — counts, casualties — require Tier 1–2 sources (sources.md sourcing floor); numbers are exactly what secondary retellings garble. The primary was not reachable at capture time: the IAEA overview page (iaea.org/newscenter/news/goianias-legacy-two-decades-on) returned HTTP 402.

What would answer it

• The IAEA's 1988 report The Radiological Accident in Goiânia (the definitive primary account) for the contamination count, the number of acute deaths, and the treatment timeline.
• Failing full-text access, a Tier 1–2 secondary (peer-reviewed radiation-medicine literature) citing the IAEA figures.

Until confirmed, the figures keep the [unverified-quant] flag and the claim-note stays status: seedling.
