The primary purpose of the Mobile Radiation Detection Systems (MRDS) provided by the National Disaster Management Authority (NDMA) is to:

ADetect seismic activity in metropolitan areas.

BIdentify unclaimed radioactive materials and protect the public from their hazardous effects.

CMonitor air quality in capital cities.

DProvide early warning for floods.

Answer:

B. Identify unclaimed radioactive materials and protect the public from their hazardous effects.

Read Explanation:

he primary purpose of the Mobile Radiation Detection Systems (MRDS) provided by the National Disaster Management Authority (NDMA) is indeed to identify unclaimed radioactive materials and protect the public from their hazardous effects.

The MRDS are specialized vehicles equipped with sensitive radiation detectors. They are used to:

  • Detect and localize sources of radiation that may have been lost, abandoned, or illegally transported.

  • Prevent the harmful exposure of people to these radioactive sources, which could pose a serious health risk.

  • Respond quickly to radiological emergencies, helping to secure the area and ensure public safety.

Identify the incorrect statement regarding landslides and their causes.

  1. Landslides are exclusively slow-moving geological phenomena that pose little immediate threat.
  2. Gravity is the fundamental force responsible for initiating and driving all types of landslides.
  3. The saturation of ground due to melting snow, combined with the snow's weight, can increase landslide risk.
  4. The removal of protective soil layers and vegetation through erosion can significantly weaken a slope, making it prone to landslides.

    Why are Disaster Management Exercises (DMEx) considered an invaluable tool for disaster preparedness?

    1. They test the capacity and readiness of all involved in preparing for any disaster, revealing strengths and weaknesses.
    2. They provide a safe, controlled environment to learn from mistakes and refine strategies without real-world consequences.
    3. They serve primarily as a historical documentation method for past disaster responses.
