Among these materials are strontium 90, which remains radioactive for 600 years and concentrates in the food chain, like other isotopes, it is tasteless, odourless and invisible. It acts like calcium in the human body, where it enters bone and lac-tatting breast. Another byproduct of the nuclear energy process is cesium 137. It too remains radioactive for 600 ears. Last but not least is the isotope plutonium.
Plutonium has a radioactive life of half a million years.
It enters the body through the lung, where it is Known to cause cancer, it mimics iron in the body. Finally, it has a predilection for the testicles, thus inducing genetic mutations in humans and other animals that are passed from generation to generation for the rest of time. Meanwhile, the plutonium itself lives on to enter testicle after testicle, lung after lung. Children are 10 to 20 times more susceptible to the carcinogenic effects of radiation than are adults. It is estimated that nuclear power by the year 2001 will have generated 1.139 tons of plutonium.
