Q

Triggers of unstable high order explosive (4)

A

heat
flame
spark
percussion

17
Q

Complete disruption or fragmentation of the body could be expected if the victim is most likely

A

in contact with the explosive

18
Q

True about effects of blast wave EXCEPT

a. the impact of high pressured wave can knock down the person
b. petechial hemorrhages on the mucosa of the trachea is due to the entry of high pressured wave along the trachea
c. The ear is the most vulnerable to the blast
d. NOTA, all are true

A

B;

” In the respiratory organ, the bronchus may be lacerated or the mucosa of the trachea ay develop petechial hemorrhages. This effect is not due to the entry of the high pressured wave along the trachea and bronchi but by its passing directly on the body wall. “

19
Q

Death or physical injuries due to detonation of high explosives may be due to the ff (5)

A

PI BAD
Poisoning by inhalation of gases
Injuries from falling debris

Burns from the flame or heated gas
Asphyxia due to lack of oxygen
Direct injury by the flying missiles

20
Q

Explosives that may cause shrapnel wound (4)

A

Grenade
Bomb
Mines
Exploding missiles

21
Q

Identification of the site of explosion and collection of evidences (3)

A

Crater
Scrapings
Fragments

22
Q

Color spot test reagents (3)

A

Griess reagent
Diphenlyamine Reagent
Alcoholic KOH Reagent

23
Q

Other tests on extract (3)

A

Infra-red spectrophotometry
X-ray diffraction
Gas chromatographic analysis

24
Q

Place of atomic explosion(3)

A

Aerial explosion
Ground
Subamarine

25
Q

Rays emitted by radioactive substances during explosion (4)

A

Alpha
Beta
Gamma
Neutron

26
Q

Composed of positively charged helium, having a high linear energy transfer with a poor penetrating power that can be stopped by a sheet of paper

A

Alpha rays

27
Q

Uncharged and composed of highly penetrating particles and basic element in nuclei of atoms

A

Neutron Rays

28
Q

Composed of short rays with high energy and greater penetrating power and like neutrons it extends a significant distance and causes much damage to the human body

A

Gamma rays

29
Q

Composed of positively or negatively charged electrons with a higher penetrating power than the alpha rays but the ionizing power is much less. The electrons are travelling at a very high velocity and in some cases approaching the speed of light.

A

Beta rays

30
Q

Characteristics of nuclear bomb explosion that distinguishes it from conventional High Explosive bomb explosion (3)

A
  1. Many thousand times as powerful as a high conventional bomb explosion
  2. a large proportion of its energy is emitted as thermal radiation
  3. The explosion emits a highly penetrating and harmful radiation
31
Q

True of atomic explosion and its effects to the human body
a. the effects of atomic explosion of the human body are directly proportional to the distance

b. The effects of atomic explosion are the same as that of ordinary chemical bomb explosion, and same intensity
c. aside from the immediate traumatic effects, the radiation emitted by the radio-active substances can also have an effect which may be local or general
d. All are true

A

D

32
Q

General effects of atomic explosion (3)

A
  1. Massive dose causes generalized erythema, disorientation followed by coma and death
  2. Lesser dose may cause nausea, vomiting followed by prostration and rapidly developing and persistent leukemia
  3. Later symptoms may develop in the form of rise of temperature, ulceration of lymphoid, easy fatigability, oropharyngeal ulceration and severe leukopenia
33
Q

Factors responsible for the effect of B radiation (5)

A 
Age
Dosage
Kind of radiation
Fractional doses
Sensitivity
