What is required for activated-charcoal adsorption (AC) devices to function?

• A. Power
• B. Manual operation
• C. No power
• D. Continuous monitoring

Answer: (C)

Activated-charcoal adsorption devices function through a passive process that does not require an external power source. These devices rely on the adsorption of radon gas onto the surface of activated charcoal, which is a type of carbon that has been treated to enhance its absorbent properties. In this approach, air containing radon is drawn into the device and comes into contact with the activated charcoal, allowing radon atoms to adhere to the charcoal’s surface due to physical and chemical interactions. The simplicity of this mechanism enables these devices to operate without the need for electricity or any external power, making them convenient for home use and extending their versatility in various environments. The other options—requiring power, manual operation, or continuous monitoring—do not align with how activated-charcoal adsorption devices are designed to operate. These devices are specifically designed to be self-sufficient and require minimal user intervention, relying solely on the passive capture of radon without any active mechanical processes.
