Which of the following is an acceptable method for disposing of low activity gas?

The disposal of low activity gas is governed by regulations that aim to minimize environmental impact while ensuring safety. Releasing low activity gas to the atmosphere, under controlled conditions and in compliance with regulatory limits, is an acceptable method. This approach typically involves ensuring that the radioactivity levels and the volume of gas being released are sufficiently low to pose no significant risk to human health or the environment.

Monitoring and proper procedural controls are essential to ensure that the release does not exceed permissible limits, making it a practical and safe option when managed correctly. Unlike some other disposal methods, releasing to the atmosphere avoids the complications and potential hazards associated with physical containment or surface interactions found in options such as compressing and burying or discharging in open water.

It is important to be aware that the other disposal methods presented are not acceptable due to various environmental and safety concerns. For example, compressing and burying could lead to unforeseen hazards if the gas were to leak or if the containment became compromised. Discharging in open water can contaminate water sources and pose risks to aquatic life and ecosystems. Flaring in open space may create air quality issues and is generally reserved for certain types of gases where combustion is an option and not for radioactive materials. Thus, releasing low activity
