{'noble gas': [2, 0, 0, 0], 'helium': [0, 0, 1, 0], 'cancer treatment': [1, 0, 0, 0], 'krypton': [2, 0, 1, 0], 'neon': [1, 0, 1, 3], 'radon': [0, 0, 0, 1]}
The correct answer is option 2, Radon.
Cancer treatment is done using radiation therapy, which involves the use of ionizing radiation to kill cancer cells. Radon, which is a radioactive noble gas, is sometimes used in radiation therapy for certain types of cancer. It emits alpha particles, which have high energy and can penetrate tissues to target cancer cells. This radioactive gas is produced naturally from the decay of uranium in soil, rocks, and water. However, it is important to note that the use of radon in cancer treatment is not common and is limited to specific cases. Other noble gases listed in the options (Helium, Krypton, and Neon) do not have radioactive properties and are not used in cancer treatment.
