As any exposure to ionising radiation could potentially damage cells and lead to cancer, . w. hen handling radioactive materials and in situations where workers are exposed to ionising radiation the ALARA principle should be employed..

Authorized users (AUs) must have adequate training and experience with the types and quantities of licensed material that they propose to use.. When sedimentary rock is deposited in layers it is deposited horizontally.. Scientists use this “Principle of Original Horizontality” to help them determine the age of the layers.. The older layers of rock are found below the younger layers of rock.. i w wartoci w pokarmow and food samples was carried out in Poland in 1994 results were compared to the the period 1985 - 1993 the Chernobyl accident gradual decrease of contamination been observed The adioactivity is a part of nature Everyatoms are unstable that is they have toomuch energy When radioactive atoms spon-taneously release their extra energy they areeventually though they do not all dec What are they? . exposure … contamination.
