among tha people who have raceived radiation, they would be no different from those that appear in other people around tha world. that a radioactive elemant The scientists have found that aame from the atomic bomb testa asn cause canoer in tha throat (in the thyroid).

In a commmity in which people have received radiation, thare might be am increase in the nunber of ohildren bom with defects. THE WAYS THAT SCLENTISTS KNOW THE AMOUNT OF RADIATION A PERSON RECELVES Everybody in the world has some radioactive materials in their body. Peaple cannot know by themselves how much radiation ia in any thing or in their badiles because they cannot see fk, hear it, taste it, amell it, or feel jk. Only instruments can raeveal things that measuring are the radioactive in radiation that this. There are instruments the soil and in food; aomes from the soil. for measuring there are those for Scientists use these {natrumenta to gat information in order to be able to estimate the amount of radiation that people can raceive if they live in an area containing radioactiva things. The picture at the left shows the instrument that asctentints use to measure the anount of gamma radiation that comes from radioactive materials in 8
