Radiation Robot Makes Troops Safer 134
Darkman, Walkin Dude wrote to mention a plucky little radiation-proof robot working to make life easier for folks in the military. From the article: "By this time an hour and a half had gone by, and the team was temporarily out of ideas. Phil had estimated that the robot could remain ambulatory in the radiation field for only 50 minutes, and in fact the robot's lower portion was no longer responding to commands. The RAP team, as a precaution against this very circumstance, working with White Sands personnel had tied a rope to M2 before sending it into the work area. The rope, attached to a RAP team winch 100 feet outside the structure, ensured the robot could be hauled out if radiation damaged its drive unit. But radiation shields now blocked a direct haul. M2 was hemmed in. Using a ten-foot-long pole and standing at the edge of the field (which fanned out like a flashlight beam, strongest at its center and weakest at its edges), team members hooked and then tugged at the rope hauling M2. The deflection of the rope's pull slid the robot around a moveable radiation shield without knocking it over. The RAP team's winch then pulled the robot directly out. "

Wise to the design of robots, Sarah and her son, future savior of humankind John Connor, shoved the robot through a nearby doorway conveniently located right above a steel foundry where it dramatically screamed in electronic pain for a few seconds. And then it was over.
"Is it over, mom?" John asked, panting.
Sarah Connor wiped the sweat out of her eyes. "It's over," she said as the familiar industrial movie soundtrack theme began to play. "It's over."

"There are many different types of radiation effects, many of which cause both mechanical and electrical degradation.

Electrical degradation would physically occur during operation. Due to the accumulation of alpha particles, bits can be flipped during operation and cause system failure"

Well there are four types of nuclear radiation - you usually get only one or two of these, depending on the cause.
Alpha particles are ionized helium nuclei - they are highly energetic and fast but lose speed quickly in air and do not penetrate solids. These do not affect unexposed electronics
Beta particles are high speed electrons. These can penetrate thin shields and have an ionizing effect on materials. These could with enough exposure affect elect

As for nucleur power plants, I think it'd be best not to increase the use of remote robots. The more human inspection is required, the more shielding they have to use, which imho is a good thing.
