Chernobyl evidence: INSAG and UNSCEAR

The first weeks produced a propaganda fog. The lasting file is IAEA, UNSCEAR and later Ukrainian and Russian archives.

Dose maps and thyroid registries are stronger than any single cinematic control-room scene.

Exhibits

Exhibit A

Inquiry

First international cause statement, operator-centred, written before full RBMK design data were on the table.

Exhibit B

Inquiry

The revision that English technical references now prefer: design, rods, void coefficient and safety culture.

Exhibit C

Document

Dates the 134 ARS cases, 28 early radiation deaths and the thyroid-cancer rise among those who were young in 1986.

Exhibit D

Testimony

Public sessions in the Chernobyl area produced convictions of plant managers under Soviet criminal law.

Exhibit E

Physical

The 1986 sarcophagus and the 2016 arch are themselves evidence of what remained in unit 4 and of the international funding trail.

Exhibit F

Statute

The 1986 and 1994 treaties are the legal imprint of the late admission and of the demand for a named safety culture.

Engineering cause

INSAG-7 plus later RBMK studies give a stable technical account.

Early death record

UNSCEAR’s ARS cohort is tightly documented; the 30/31 official early figure is stable.

Long-term health models

Thyroid cancer is attributed; broader cancer and ‘liquidator’ totals remain model-dependent.

Political archive

Glasnost-era and post-1991 files opened much, not all, of the first-week decision chain.

The evidence is strong on how unit 4 failed and weaker on any single lifetime death total.

Public-record encyclopedia. Not legal advice. Not a how-to. Graphic detail is withheld. Wars belong in a separate atlas.
