Radioactive capsule found in Australia could have been deadly with prolonged exposure, expert says - ABC News

The health effects of coming into interaction with a radioactive capsule nary bigger than a coin that was mislaid successful Western Australia -- and has since been recovered -- could perchance beryllium severe, according to experts.

Caesium-137 is simply a human-made fission task often utilized successful radiological laboratories arsenic good arsenic successful concern settings, specified arsenic wrong gauges successful mining operations, Angela Di Fulvio, an adjunct prof of atomic engineering astatine the University of Illinois Urbana-Champaign, told ABC News.

Erythema, oregon reddening of the skin, would beryllium among the archetypal symptoms, and the severity of the effects increases dramatically with vulnerability time, she added.

Exposure to the radioactive substance could besides origin radiation burns oregon radiation sickness, according to the DFES.
