48 years ago I was part of a care team maintaing life in individuals who had been administered
single exposure ionizing radiation from cobalt-60 guaranteed to prove 100% lethal if their bone marrow transplant failed-
survival prospects-~~~25% team leader was awarded nobel prize--1990-- Dr Don Thomas
Chernobyl 1986--600,000 human liquidators participate in cleanup-containment--70,000 of that number
have perished -- direct consequence of exclusion zone exposure
focus of this thread is death of mechanized machinery employed in Chernobyl cleanup
first---a few questions--
what energy particles proved most lethal to Chernobyl robots?---
answer--gamma rays
what solid state components were most susceptible to Chernobyl radiation?
answer--prom chips and ccd cameras--life expectancy of minutes
what commonly used polymer degraded fastest at Chernobyl?
answer--Teflon
what additive blocked optical glass /fiber optics data transmission lines from destruction
consequence of radiation opacity?
answer--cesium salts at 2%
what is identity of the single Chernobyl robot that did not succumb to radiation death?
answer--MOBOT--designed at Moscow State University--it contained no electronic control elements-
entirely electro-mechanical--it performed 1000 hours on reactor 4 roof
pics--Mobot and robotic DET250 dozer --
