Is a grenade deadlier underwater?

However, an underwater explosion transmits pressure with greater intensity over a longer distance. If you stood outside of shrapnel range for an exploding hand grenade, you'd likely remain unharmed. If you stood at the same range to an underwater explosion, the pressure wave would probably kill you [source: Landsberg].

Can you survive diving on a grenade?

It requires immeasurable bravery and selflessness to carry out an act for which death is all but guaranteed, but in several instances throughout history, exemplary service members have dived on grenades and survived the explosion.

Are shockwaves more powerful underwater?

Due to the elastic properties of water, the shock wave tends to be of shorter duration, but with a proportionally larger peak overpressure. The energy in the underwater shock wave attenuates very quickly with range.

Does water protect you from an explosion?

Particularly, in case of a confined explosion, water has the potential to mitigate the shock pressure as well as the gas pressure loading developed inside the structure confining the explosion. In case a high explosive detonates, a high pressure blast wave will be generated which moves outward in all directions.

Does being underwater protect you from a shockwave?

Not at all. Shockwaves are pure energy moving through whatever medium in order to dissipate by changing forms. Shock waves in water could do one great damage if they are in the water as well.

How to Survive a Grenade Blast

What happens if a grenade explodes underwater?

However, an underwater explosion transmits pressure with greater intensity over a longer distance. If you stood outside of shrapnel range for an exploding hand grenade, you'd likely remain unharmed. If you stood at the same range to an underwater explosion, the pressure wave would probably kill you [source: Landsberg].

What happens if a nuke blows up underwater?

Underwater nuclear explosions have actually been done. There were no tsunamis or massive destruction. There would be no large human death toll except ships and submarines in the immediate area. Lots of sea creatures would die in the explosion, of course, but the overall effects are much less than an atmospheric test.

Where is the safest place in the US during a nuclear war?

Some estimates name Maine, Oregon, Northern California, and Western Texas as some of the safest locales in the case of nuclear war, due to their lack of large urban centers and nuclear power plants.

Why are explosions stronger underwater?

Since the mechanical impedance of water is much higher than air, underwater blasts travel large distances before attenuating sufficiently to be harmless. When underwater blast waves interact with marine structures, they can cause significant plastic dissipation and fracture.

Where is the safest place during nuclear war?

The Smart Survivalist named the Nordic country as the safest place in the event of a nuclear war. “Because Iceland is isolated from the rest of the world by the North Atlantic Ocean, it would be very difficult for a nuclear missile to reach Iceland without being detected first,” it said.

What is the most common organ injured in underwater explosion?

Lung Injury

It is the most common fatal primary blast injury among initial survivors. Signs of blast lung are usually present at the time of initial evaluation, but they have been reported as late as 48 hours after the explosion. Blast lung is characterized by the clinical triad of apnea, bradycardia, and hypotension.

Can you survive nuclear blast underwater?

Can you survive a nuclear blast by hiding underwater? Nope. Water, being incompressible, propagates a blast wave much more readily than air. Water would provide more protection from radiation but much less protection from a blast.

How deep does shockwave penetrate?

ESWT is a relatively new treatment modality for musculoskeletal conditions. It is a noninvasive but powerful treatment providing a deeper penetration of up to 50 mm of human tissue,24 which is deeper than that of conventional ultrasound therapy.

What do seals yell when they throw a grenade?

“Hooah, Sarge.”

How close is a grenade lethal?

What is the lethal killing distance of a grenade? Without body armour or protection, a single grenade can kill an individual up to 10 metres away and can cause serious injuries up to 20 metres away. Shrapnel can reach as far as 200+ metres distance from the detonation point.

What is the strongest explosion ever recorded?

Among the largest human-caused explosions on record, a Soviet superweapon called Tsar Bomba tops the list. Meanwhile, the biggest explosion with a terrestrial origin came from the climate-altering Toba supervolcano more than 70,000 years ago.

Can you create a tsunami with a nuke?

Conceivably tsunami waves can also be generated from very large nuclear explosions. However, no tsunami of any significance has ever resulted from the testing of nuclear weapons in the past. Furthermore, such testing is presently prohibited by international treaty.

What is the most powerful explosion on earth?

On October 30, 1961, Tsar Bomba was detonated in the atmosphere at 11:32 Moscow Time over the Mityushikha Bay Nuclear Testing Range in the northern Arctic Circle. The bomb was set by barometric sensors to detonate at 13,000 feet and was dropped from a height of 34,000 feet.

What city would get nuked first?

The cities that would most likely be attacked are Washington, New York City and Los Angeles. Using a van or SUV, the device could easily be delivered to the heart of a city and detonated.

What US cities would Russia target?

Irwin Redlener at Columbia University specialises in disaster preparedness and notes that there are six cities in the US that are more likely to be targeted in a nuclear attack – New York, Chicago, Houston, Los Angeles, San Francisco and Washington DC.

Are parts of Hiroshima still radioactive?

The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.

Would I survive a nuke in my basement?

The safest place in your home during an radiation emergency is a centrally located room or basement. This area should have as few windows as possible. The further your shelter is from windows, the safer you will be.

How deep underground do you have to be to survive a nuke?

BUILD UNDERGROUND

Building down to a depth of about ten feet will provide ample protection, but any deeper makes it hard to dig out in the event of a collapse.

How far to avoid nuclear fallout?

But a new study finds that some people two to seven miles away could survive—if they're lucky enough to find just the right kind of shelter.
