from the sky in the form of cosmic rays from radama material in the atmosphere from radioactive uranium found in the water which you don't let and the earth on which you now live they aren't powerful enough to bother operator they're less of a hazard than the rays of the sun which if eric they take them down to come too much of a good thing radioactivity is represented by the ball causes electrons to be objective from their atom it's an offensive move based on ion as agent ion is they can disrupt the structure of atoms of which all living matter is composed and atoms is part of the molecule and molecules are part of the cell the cell is a structural and functional unit of all living matter a tiny machine  the human body which is engaged in the manufacture of an important product li broken through ionizing radiation the gears grind the machines father stop the factory shuts down the four kinds of missiles discharged by a radioactive substances has its own ballistic behavior to observe them attacking the body they must be symbolized far out of proportion magnified millions of time laser particles can call it service burn if the assault is sufficiently concentrated and sustained both are able to gain entry to the breathing of radioactive matter or via breaks in the skin once inside the so called hot stuff takes up residence in various parts of the body giving are highly ion izing alpha and beta particles and how long does this radio rat race go on the body will degrade in casting off some of which is the time required for fifty percent of the substance to the case with some substances it is a matter of less but a second but if you had some plutonium inside you you wouldn't make any plans to celebrate the event the various kinds of cells which make up the parts of the body never in their vulnerability to radiation most sensitive are limp cells such as those found in the tonsils next there's bone marrow which manufactured red and white blood reproduce rapidly and those of patients functioning depends on that ability are most affected radiation holds the reproduction which is a simple process of one cell dividing into two this destructiveness has been harnessed and put to work in the radium treatment of cancer which consists of cells that have gone wild and multiplied to the manifestations of radiation in the body are many and range from slight to severe loss of hair not the greedy inability of the body to resist other ailments that make its own repairs these are some of them and they may be climax by the ultimate send a fair fan in to widespread misunderstanding by sensational speculation on what radiation can do radioactivity is dangerous but to say that it's deadly serious is as misleading as giving a plant answer to the question how high is  the radium treated dial of your watch for this just harmless nuclear on a nation became a threat when man isolated such hot stuff as radium and work intimately with a broadening of scientific medical and industrial density of the material is not the way important as its ability to slow down and capture the particles concrete in the water for any good shooting the best filters and not so with an underwater however and presumably in the event the underground then service explosion they area is contaminated with radioactive material which gives all alpha and beta product and gamma rays the perpetrators of these inside job including only food which has been inspected and passed on guarding against breathing radioactive dust carrion handling contaminated articles such as clothing watching them or disposing of them badly contaminated thorough cleaning at specially the hair and under the na sound medical practice demands not only a knowledge of the way harmful agents operate but an accurate estimate of those agents radioactivity is detected by various instruments such as this guy counter it takes a very special combination of circumstances to cause the death of a person by radiation a combination that the remote possibility an ordinary work with radioactive material and not nearly so frequent in  seeking to supplement symptomatic with specific gravity the atomic bombing of hiroshima and nagasaki took the japanese completely by surprise their medical facilities were pretty well knock to the bombs radioactivity made up a small part of the talking about fifteen percent it is reasonably assumed that many who weren't killed by the bomb other destructive forces sustained radiation doses that have proved fatal in short they were burned into oblivion before they had a chance to die from radiation which put the thing or squarely upon one of the major policies in the public attitude toward atomic weapons you must concentrate on the blast the back of an a bomb it's probably been devastating it causes a gigantic rearrangement of things a complete change of scenery and means sudden death that all those who chanced to be in the way when it happened don't forget the fires that followed consider the heat which changes the complection of all that it's right there in mind always a blast and already a bombs most powerful weapon at war two conventional bombing which some of you may have experienced and you did all right down with a case of lead poisoning but that he that to get an extra hol would be symptomatic to pay by the condition would only be temporary your hair would come back same color same coll
