Identify the material, device, or invention being described in each statement. Use the letter clues to complete the names.
1. _a_iu_ - This is a crucial tool in radiation therapy for treating tumors.
2. in_and__ce_t - This invention by Thomas Edison produced a long-lasting and affordable light source.
Answer (2)
Here are the answers to the clues provided:
a_iu - This term completes to " Cobalt-60 ". Cobalt-60 is a radioactive isotope that is a crucial material in radiation therapy, specifically known for its use in treating cancerous tumors. In radiation therapy, Cobalt-60 sources are used in machines called cobalt units to deliver gamma rays to target tumors, carefully administering doses that are harmful to cancer cells but sparing healthy tissues.
in_and__ce_t - This word completes to " Incandescent ". The incandescent light bulb was perfected by Thomas Edison in the late 19th century. His version of the invention became commercially viable and was significant because it provided a long-lasting and affordable source of light. Edison's work on the incandescent bulb included finding a suitable filament material and creating a vacuum within the bulb to allow it to last longer without burning out. This invention played a significant role in lighting homes and buildings around the world, thus changing the way people lived and worked after dark.
The answers to the clues are Cobalt-60, a vital material in radiation therapy for cancer treatment, and Incandescent, relating to Edison's light bulb invention. Cobalt-60 is chosen for its role in medical applications, while Incandescent highlights technological innovation in lighting. Together, they illustrate significant advancements in health and technology domains.
