What an interesting question. The answer is however complex.
It is possible to make small amounts of some radioactive elements or radioactive isotopes of some elements in a laboratory (usually involving a nuclear pile or an accelerator). For instance the element Plutonium is made this way.
(Other radioactive elements are produced naturally by the radioactive decay of heavier radioactive elements)
However, making a radioactive element or isotope from scratch requires the application of an enormous amount of energy. The place where all elements heavier than the element Iron (Fe - Atomic number 26) are made is in stellar explosions, the death of stars 8 or more times more massive than our Sun, called "supernovas".
It is in supernova explosions that the radioactive elements are made.

What are all the elements of radioactive?
Uranium.
What is a series of radioactive elements?
dgaf
What made marie curie discover polonium?
Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
What is a radium and a polonium?
Radium and polonium are radioactive natural chemical elements.
One of the most radioactive elements discovered by the curies was uranium?
No. The Curies did not discover uranium. They discovered polonium and radium, of which polonium is more radioactive.
How many elements are made only in a laboratory?
How many radioactive elements are made only in a laboratory?
How Many Radioactive Elements Are Made in the Laboratory?
About 28 elements were discovered in the laboratory. But after the man made preparation some elements were discovered also in nature in very extremely traces: Pm, Tc, Pu, Np, Am, Cm, Bk.
What must be done to ensure DNA in a laboratory is radioactive?
Incorporating radioactive nucleotides must be done to ensure that DNA made in a laboratory is radioactive.
What made up all radioactive elements?
After disintegration all radioactive elements are transformed in other elements.
What is radioactive elements made of?
actinides
Are some elements that have been made by scientists under laboratory?
Yes, Some elements that have been made by scientists under laboratory.
What elements is radioactive and synthetic well the answer is mendelevium?
Yes, mendelevium is man made and radioactive.
What is made up of all radioactive elements?
The actinides
What is made up of radioactive elements?
ADADAD
What are synthesizers?
Synthetic elements are unstable chemical elements not naturally found on the earth. They are synthesized in the laboratory. All of them are unstable and radioactive in nature, which means they emit radiations and decay into other elements.
How does artificial transmutation differ from artificial radioactivity?
"Artificial transmutation" is a nuclear reaction induced in laboratory, its man made. Artificial radioactivity is a radioactive disintegration phenomenon supported by artificial isotopes.
What family is made up of all radioactive elements?
The actinides
