The damage caused would be internal, with the injurious effects appearing over many years. Why? Because of radioactive contamination from long-lived radioactive isotopes like strontium-90 or cesium-137, which can be concentrated through the food chain and incorporated into the body. Even so, beyond the blast radius of the exploding weapons there would be areas (“hot spots”) the survivors could not enter. Most of the bomb-produced radionuclides decay rapidly. Other hazards are strontium-90, an electron emitter with a half-life of 28 years.Īnother example of the seriousness, besides the obvious immediate deaths within the blast zone, quoted from … It is readily taken into the blood of animals and humans and may get into the tissue. Probably the most serious threat is cesium-137, a gamma emitter with a half-life of 30 years. Listen, I’m not downplaying the effects! There’s way more to this. (source: Fallout from a Nuclear Detonation:Description and Management) (from the time of the explosion, not from the time of fallout deposition) Rate of Decay of the dose rate from radiation from fallout That’s a good thing.įallout gives off more than 50% of its energy in the first hour and continues to decay rapidly even after that initial hour. It could go a long way.Įventually it will decay. Slowly, the effects of gravity and weather will bring it to the ground. Other fallout will be suspended into the atmosphere. It will eventually settle across the affected land.įollowing the explosion, fallout will be especially concentrated near the detonation zone. Alpha/Beta Radiation attaches with these particles. Pulverized particles from the detonation interaction with the ground, buildings, etc. Here’s the NBC-77 SOF.Ĭertified CBRN filter 40 mm NATO with Longest shelf life: 20 yearsĪ nuclear fallout cloud. The gas mask shown above will accommodate two filters, though you only need one to function. And, they too should be CBRN or NBC approved. MIRA SAFETY M CBRN Full Face Reusable Respirator-MaskĪlso, you will need gas mask filters. That’s where a gas mask for nuclear radiation comes in. The problem is this… You don’t want to breath it! Why? Because once it gets inside your body, your internal organs will be radiated. Beta radiation can also be stopped by wearing heavy clothing (for example). In fact, alpha radiation is stopped by the skin on your body. ![]() They are both low energy particles compared to very high energy gamma. Gas Mask To Stop Alpha and Beta RadiationĪlpha and beta radiation. The term CBRN is a replacement for the cold war term NBC (nuclear, biological, and chemical), which had replaced the term ABC (atomic, biological, and chemical) that was used in the fifties. ![]() ![]() CBRN or NBC Approved Gas Mask for Nuclear Fallout (and Chemical – Biological)Ĭhemical – Biological – Radiological – Nuclear It’s an important part of one’s personal protective equipment (PPE) in this regard. That is, with a proper gas mask, fitted properly to your face.Ī gas mask is integral to survival for many circumstances and situations beyond nuclear alpha particle radiation too (chemical / biological). However, Alpha & Beta radiation (which is in the ‘fallout’ cloud) is stopped from getting into your lungs. There are lots of factors and variables of your situation which will impact your survival and plan-of-action. A gas mask for nuclear fallout is not a magic bullet. Neutron radiation is similarly unaffected by gas masks. Gas masks provide no protection against gamma radiation. First, will a gas mask really protect you from nuclear fallout?
