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. ![]() With that said, Alpha & Beta radiation (which is in the ‘fallout’ cloud) will be stopped from getting into your lungs while properly wearing the right gas mask for nuclear fallout… and the right filter.Ī gas mask is integral to survival for many circumstances and situations beyond nuclear alpha particle radiation too - chemical / biological (e.g. 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. So lets talk about what’s the best gas mask for this scenario.ĭo bear in mind that gas masks provide no Gamma radiation protection. While inhaling nuclear fallout won’t ‘get you’ in 3 minutes, it certainly will ‘get you’. You might say that 3 minutes without it, and, well, not good. The ‘Rule of 3’ for survival (link at the end) reveals that AIR (breathing) is firstly the most important factor to mitigate. Additionally, high altitude fallout may potentially spread quite far. First, will a gas mask really protect you from nuclear fallout? To an important extent, yes for Alpha and Beta radiation within a nuclear fallout ‘cloud’ – which may spread far and wide depending on wind currents.
