text_A: Snoop Dogg has a book called Da Game Is to Be Sold, Not to Be Told.
text_B: Activation products are materials made radioactive by neutron activation .. neutron activation. neutron activation. Fission products and actinides produced by neutron absorption of nuclear fuel itself are normally referred to by those specific names , and activation product reserved for products of neutron capture by other materials , such as structural components of the nuclear reactor or nuclear bomb , the reactor coolant , control rods or other neutron poisons , or materials in the environment .. Fission products. Fission products. neutron absorption. neutron absorption. nuclear fuel. nuclear fuel. neutron capture. neutron capture. nuclear reactor. nuclear reactor. nuclear bomb. nuclear bomb. control rods. control rods. All of these , however , need to be handled as radioactive waste .. radioactive waste. radioactive waste. Some nuclides originate in more than one way , as activation products or fission products .. Activation products in a reactor 's primary coolant loop are a main reason reactors use a chain of two or even three coolant loops linked by heat exchangers .. Fusion reactors will not produce radioactive waste from the fusion product nuclei themselves , which are normally just helium-4 , but generate high neutron fluxes , so activation products are a particular concern .. radioactive waste. radioactive waste. helium-4. helium-4. Activation product radionuclides include  :. radionuclides. radionuclides. -LSB- 1 -RSB- Branching fractions from LNHB database .. -LSB- 2 -RSB- Branching fractions renormalised to sum to 1.0 .
