megaton weapon การใช้

• There were also other factors involved in the decision to build an Interim Megaton Weapon.
• Nigel is instructed to plant the 50 megaton weapon and leave ( so it can be detonated ).
• Knobkerry, alias Green Grass, alias Interim Megaton Weapon, alias Violet Club and Yellow Sun Mk . 1 had one other distinction.
• In response to the public alarm over fallout, an effort was made to design a clean multi-megaton weapon, relying almost entirely on fusion.
• Those who previously had doubted whether a fission-fusion bomb would be feasible at all were converted into believing that it was only a matter of time before both the USA and the USSR had developed multi-megaton weapons.
• Being able to penetrate underground increases its effectiveness against buried targets, as it more efficiently transmits explosive energy through enhanced ground-shock coupling, allowing its max yield of 50 kilotons underground to have the equivalent surface-burst capability of a 750 kt to 1.25 megaton weapon.
• Delays and failures in the Granite programme and the abandonment of Green Bamboo without a test, left a gap in the programme and an emergency capability weapon to fill that gap was devised from elements of both Green Bamboo and Orange Herald; being known as Knobkerry, or Green Grass, and the Interim Megaton Weapon.
• In this example, as there is now a 45 % reduction in the amount of heat experienced by one ducking and covering, the median lethal thermal range from this 1-megaton weapon can now be more accurately described as equivalent to absorbing the entire flash energy from a 0.55 Mt or 550 kt weapon, if one ducks and covers in 2 seconds.
• However, for one caught in the open outside this ~ 3-kilometer radius from ground zero from a 1-megaton weapon, ducking and covering would drastically increase one's chance of survival, as at this range the radiation hazard is near zero, whereas that from the blast is a chance of 50 % fatality at a ~ 7.5 km range and that of thermal effects 11 km.
• If someone was caught in the open, and by surprise, by the same 1-megaton weapon detonation, but ducked and covered in 2 seconds time from first noticing the moment of flash, then that person would have prevented themselves from being exposed to the full brunt of the 1-megaton explosion's thermal energy; instead, approximately 55 % of the explosion's total thermal flash energy would have been absorbed over these 2 seconds.
