Mercaptoethylamine 11.29) (cysteamine) effectively prevents radiation injury. It has been shown that, in a mouse irradiated with 750 rad (whole-body single dose), significant increases of iron and copper occur in the bone-marrow, adrenals, spleen, liver, lungs, and thymus, and of iron in muscle and kidney (Yendell, Tupper and Wills, 1967). One school of thought assigns the radio-protective properties of cysteamine to its ability to sequester the heavy-metal cations released from cells by irradiation Qones, 1960). Other hypotheses are summarized by P. Brown (1967).

At the frequencies allocated for industrial, scientific and medical purposes between 13.56 and 40 680 MHz, those used for heating applications at 13.56, 27.12, 896 and 2450 MHz are in general use for domestic, commercial and industrial purposes. They may employ substantial field strengths that could cause severe burn injuries, so precautions are necessary to contain the radiation and prevent access into wave guides and resonant chambers and between applicators when the apparatus is energised. This is effected by bolted-on covers which require tools for their removal, or access doors interlocked with the supply so that the supply is off when the door is open.

The worst nuclear power accident in the U.S. occurred at the Three Mile Island plant in Pennsylvania. In this accident no one was killed and no one was directly injured. The event at Three Mile Island occurred from faulty instrumentation that gave erroneous readings for the reactor vessel environment. A series of equipment failures and human errors along with inadequate instrumentation allowed the reactor core to be compromised and go into a partial melt. The radioactive water that was released from the core was confined within the containment building and very little radiation was released. In the Three Mile Island incident, the safety devices worked as planned and prevented any serious injury. This accident resulted in improved procedures, instrumentation, and safety systems being implemented.
