QUESTION 18 Choose all of the statements about nuclear reactions that are false. The relative biological effectiveness (RBE) is 10 times greater for gamma radiation than for alpha radiation. Gamma radiation only changes the atomic number but not the mass number of a nucleus. The energy produced by the sun is the result of nuclear fusion. ORadioactive decay is a first order kinetic process. The neutron/proton ratio of stable nuclei increases with increasing atomic number. OUESTION 19
