Fission Room Radiation Indicator

A handheld device mounted near the reactor core display, its needle flickers within safe parameters despite the room’s devastation. Its dial shows 'Normal' radiation levels, contradicting Professor Watson’s assumption that lethal contamination would remain after Eldrad absorbed the un-explosion. The Doctor and Sarah Jane refer to it as proof Eldrad’s absorption worked, while Watson’s frustration underscores its role in challenging immediate military action.

Purpose

To monitor real-time radiation levels in the fission chamber and verify containment integrity following nuclear reactions.

Significance

Serves as critical evidence in the ideological clash between The Doctor’s restraint and Watson’s demand for force. Its readings prevent escalation and buy time for diplomacy, making it a pivotal tool in shaping the trio’s strategies.

S14E7 · The Hand of Fear Part 3

Eldrad takes control of the reactor core

The radiation indicator mounted near the core displays ‘Normal’ readings despite Watson’s expectation of lethal contamination, providing visible proof for the Doctor’s theory that Eldrad absorbed the un-explosion’s energy and is now controlling residual radiation.

Before: Flickering red vital signs post-explosion

After: Stable green at ‘Normal’ as Doctor points to it as evidence

S14E7 · The Hand of Fear Part 3

Doctors clash over Eldrads escape

The Fission Room Radiation Indicator needle points to 'Normal', contradicting Watson’s expectation of lethal radiation contamination. It becomes crucial evidence in the Doctor’s argument and a source of contention that drives Watson to desperation and retreat.

Before: Showing signs of system stress from the un-explosion, but still functioning.

After: Functionally accurate, displaying 'Normal' radiation levels despite devastation within the core.
