Quick Answer: During Which Post Disaster Phase Do Survivors Realize That They?

What are the four steps of emergency response?

Current thinking defines four phases of emergency management: mitigation, preparedness, response, and recovery.

There are entire courses on each of these phases..

What is c4 made of?

C-4 is made up of explosives, plastic binder, plasticizer and, usually, marker or taggant chemicals such as 2,3-dimethyl-2,3-dinitrobutane (DMDNB) to help detect the explosive and identify its source.

What are the advantages of disaster management?

There are real benefits to being prepared: People also can reduce the impact of disasters (flood proofing, elevating a home or moving a home out of harm’s way, and securing items that could shake loose in an earthquake) and sometimes avoid the danger completely.

Which organ is most radiosensitive?

The digestive tract is among the most radiosensitive organs in the body and its function, which is partly regulated by gastrointestinal (GI) peptides, can be affected by radiation exposure.

What is the correct order of the phases of a community disaster?

The four phases of disaster: 1) mitigation; 2) preparedness; 3) response; and 4) recovery. The model helps frame issues related to disaster preparedness as well as economic and business recovery after a disaster.

How do you know what type of radiation is emitted?

To determine the type of radiation (alpha, beta or gamma), first determine the background count rate, then the source count rate with no absorber. Next, place a sheet of paper between the source and the monitor. If the counts are significantly reduced, the source emits alpha particles.

What is the goal of disaster management?

Goals of Disaster Management: Disaster management aims to reduce, or avoid, the potential losses from hazards, assure prompt and appropriate assistance to victims of disaster, and achieve rapid and effective recovery.

Which body part is most sensitive to radiation?

For example, since the blood forming cells were one of the most sensitive cells due to their rapid regeneration rate, the blood forming organs are one of the most sensitive organs to radiation. Muscle and nerve cells were relatively insensitive to radiation, and therefore, so are the muscles and the brain.

What element is the most explosive?

AntimonyAntimony – THE MOST EXPLOSIVE ELEMENT ON EARTH!

What type of explosive is widely used by the military?

Trinitrotoluene. TNT is the most common military explosive.

What are the 4 phases of disaster management?

Emergency managers think of disasters as recurring events with four phases: Mitigation, Preparedness, Response, and Recovery.

What is the most powerful explosive in the world?

PETN is a powerful explosive material with a relative effectiveness factor of 1.66. When mixed with a plasticizer, PETN forms a plastic explosive. Along with RDX it is the main ingredient of Semtex.

What materials can block radiation?

Non-lead shielding materials are manufactured with additives and binders mixed with attenuating heavy metals that fall into the same category of materials as lead that also absorb or block radiation. These metals may include tin (Sn), antimony (Sb), tungsten (W) bismuth (Bi) or other elements.

What form of ionizing radiation can penetrate deeply?

Beta particles are much smaller than alpha particles, so they can travel farther and penetrate deeper. Beta particles are sometimes used in eye surgery. Gamma radiation and x-rays, are high-energy waves that can travel great distances at the speed of light. Both can penetrate deeply into matter.

How does alpha radiation affect the body?

Alpha particles lack the energy to penetrate even the outer layer of skin, so exposure to the outside of the body is not a major concern. … The ionizations they cause are very close together – they can release all their energy in a few cells. This results in more severe damage to cells and DNA.

What are the 3 stages of disaster management?

The three phases of a disaster program are disaster planning, disaster management and disaster recovery.

Which part of the cell cycle is most sensitive to radiation?

Cells in late G2 and mitosis (M-phase) are the most sensitive to radiation, and cells in late synthesis (S-phase) are the most resistant (Fig.

Which cell types are least sensitive to ionizing radiation damage?

Amongst the body cells, the most sensitive are spermatogonia and erythroblasts, epidermal stem cells, gastrointestinal stem cells. The least sensitive are nerve cells and muscle fibers.
