This study is not concerned with the probability that such an enemy attack will be made. II Definitions of Terms Used HI Ground Zero - The point on the ground directly under the point of burst in the air Aiming Point -• The point on the ground directly under the point where the b;omb is aimed to be burst in the air No Rescue - No organized and trained rescue is carried out, which means effectively that only people who are not trapped or who can escape by their own efforts survive Seriously Injured - Hospitalized persons who would not report to work for a considerable period of time Lightly Injured - First Aid cases who would be able to contribute to their work a few days after the attack Nighttime - The time during which people are in their normal places of residence Daytime *• The time during which people are at their normal places of work Sources of Basic Information (a) Population Information on the daytime distribution of population Is based on a field survey of the commercial area in combination with a redistribution of the 1951 census returns in greater detail to show the residential population by individual city blocks. Information on the nighttime distribution of population is based on a redistribution of the 1951 census returns in greater detail to show the population of individual city blocks. This is considered for the purpose of this study a sufficiently good approximation to the distribution of population. \ 000117 �Document disclosed under the Access to Information Act - 1 Document divulgue en vertu de la Loi sur I'acces a I'information TOP SECRET CANADIAN EYES ONLY - 2 -• ft) Military Establishments The military establishments important to the national war effort were chosen by the Joint Planning Committee, The Establishment in the Edmonton area is listed in Appendix "Aw. (cj Vital Points Iiifbnnation on other* Vital Points was taken from the 1953 List of Vital Points, which is the work of the Interdepartmental Committee on Vital Points* The list for the Edmonton area is given in Appendix *An. (d) Scientific Data Basio data on the effects of atomic bomb explosions on people and structures was prepared by the Defence Research Board (Scientific Adviser to the Civil Defence Coordinator). IV Factors Considered in Selecting Aiming Points for Study The effects of an attack on a city vary widely with the location of the bomb burst. As it is not considered practicable to study all possible points of burst, a series of Aiming Points have been selected which are calculated to give the maximum effect on population and on different groupings of Vital points. The effects of an attack vary widely with the energy released by the bomb. As it is not possible to estimate the energy level of the bomb most likely to be used, separate estimates were made for a bomb with the lowest probable energy and the highest probable energy level. The effects on people also vary widely with circumstances of warning and rescue. A series of estimates were therefore made for different conditions of warning and rescue. The estimates made for conditions WITH RESCUE are for ideal rescue conditions with organized and trained rescue teams, in temperate climates and when the atomic attack is unsupported by other weapons. In spite of rescue efforts casualties would tend towards those given for NO RESCUE under severe winter conditions, or if Chemical warfare attack were combined with atomic attack or if the spread of fire were extensive. Conditions of visibility would also alter the effect of an attack. Poor visibility would reduce the extent of fire and the number of radiation casualties and would have some effect on the chances of pinpointing the target from the air. All calculations are based on an average clear day over a city with a visibility of about six miles. For the city of Edmonton Aiming Points were chosen to give the maximum effect on the daytime and on the nighttime distribution of population. Aiming Points were also chosen to give the maximum effect on two groupings of the Vital Points considered collectively. 000118 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information TOP SECRET CANADIAN E"YES ONLY M V 3 M Results of the Study of the City of Edmonton A daytime attack on the population of Edmonton could cause casualties among 30-45$ of the population if a 20 Kiloton bomb were used, depending on conditions of warning and rescue; 40-65$ if a 100 Kiloton bomb were used, and cause considerable damage to the Vital points. A daytime attack on the Vital Points by a 20 Kiloton bomb would result in casualties among 25-40$ or 10-15$ of the population depending on the Aiming Point considered; 40-65$ or 20-35$ by a 100 Kiloton bomb attack, and cause devere damage to those Vital points. A nighttime attack on the population of Edmonton could cause casualties ainong 25»-35$ Of the population if a 20 Kiloton bomb were Used- depending on conditions of warning ahd rescue; 35-65$ if a 100 Kiloton bomb were used. A nighttime attack on Vital Points by a 20 KHotoh bomb would cause casualties among 15-30$ Or 30-60$ of the population depending on the Aiming Points considered^ 10-15$ or 20-40$ by a 100 Kiloton bomb attack, and cause severe damage to those Vital Points. (a) Effects on Population The effect of an attack on the daytime and nighttime population is given in Tables I and II for each Aiming Point and for different conditions of warning and rescue. (M Effects on Vital Points A summary of the effect on Vital points is given in Table III for each Aiming Point. The extent of damage to Vital Points and the effect on their various functions is also described below for each of the Aiming Points, The relative importance of each Vital Point to the Canadian - U.S. war effort is indicated by the category (AA, A, B or C ) , which is given for each Vital Point in Appendix "A". A definition of each of the categories is also given in Appendix "A". 000119 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information TOP SECRET CANADIAN EYES ONLY ' - 4 « (a) Detailed Discussion of an Attack onfeachof the Aiming Points Effect of a Burst over Aiming Point # I-D - Chosen to give maximum effect on the daytime distribution of population by a 20 Kiloton bomb A daytime attack on this Aiming Point would cause casualties among 30-45$ of the population depending on condi"tiohs of warning and rescue (Tables I and II).

(d) Effects on Morale It is expected that the effect on morale in large centres of population in Canada, and at least the northern parts of the United States, would be much the same whichever city is attacked by an atomic bomb. The effect will probably be somewhat proportionate to the size ofthe casualties inflicted by individual bombs and by the number of cities attacked, VI Air Navigation Aspects of an Attack With the equipment at present available to the Russian Long Range Air Force, the approaches to Edmonton would not be easy from the pacific Ocean, the north, or the northeast, on a high or low level attack for a well trained navigator not familiar with the area. However, visual identification of Edmonton would not be difficult. Accuracy in identifying specific Aiming Points is a critical aspect. However the Vital Points are located over much of the built up area and an atomic explosion over most of the city would result in serious damage to population and Vital Points, though of a lesser magnitude than described by this report. 000125 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information TOP SECRET TkSLS I - CASUALTY ESTIMATES - CITY OF EDMONTON CANADIAN EYES ONLY DAYTIME ATTACK .20 K i l o t o n Sonfc 100 K i l o t o n Bomb Aiming Point if I - D - Chosen t o Give Maximum E f f e c t on Daytime D i s t r i b u t i o n of P o p u l a t i o n Killed Seriously Injured Lightly Injured No Warning - N» Rescue 50,200 12,900 8,500 No Warning - £ i t h Rescue 34,900 19,500 With Warning - With Rescue 28,800 14,900 Killed Seriously Injured Lightly Injured No Warning - No Rescue 86,900 18,300 10,800 11,200 No Warning - With Rescue 55,500 30,400 16,200 10,500 With Warning - With Rescue 45,600 21,000 12,300 Aiming P o i n t # 2 - Chosen t o Give Maximum E f f e c t on One Grouping of V i t a l P o i n t s No Warning - No Rescue 38,800 15,200 11,400 No Warning - No Rescue 84,700 18,600 11,600 No Warning - With Rescue 21,100 21,700 14,500 No Warning - With Rescue 48,700 32,100 18,200 With Warning - With Rescue 15,700 14,500 12,100 With Warning - With Rescue 38,600 20,300 13,200 Aiming Point § 5 - Chosen t o Give Maximum E f f e c t on a Second Crouping of V i t a l P o i n t s 10,80 0 6,700 5,300 No Warning - No Rescue 36,100 15,000 11,600 No Warning - With Rescue 5,100 8,700 6,300 No Warning - With Rescue 15,500 21,400 15,100 With Warning - With Rescue 3,500 5,800 4,600 With Warning - With Rescue 10,800 13,200 9,300 No Warning - No Rescue 000126 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information TOP SECRET TABLE I - CASUALTY ESTIMATES - CITY OF EDMONTON CANADIAN EYES ONLY NIGHTTIME ATTACK 100 Kiloton Bomb 20 K i l o t o n Bomb Aiming P o i n t // I-N - Chosen t o Give Maximum E f f e c t on P o p u l a t i o n During a N i g h t t i m e Attac k Killed Seriously Injured lastly Injured No Warning - No Rescue 36,500 11,200 7,600 No Warning - With Rescue 21,200 17,000 10,300 With Warning - With Rescue 16,600 12,300 8,900 Killed Soriosuly Injured Lightly Injured No Warning - No Rescue 76,300 16,800 10,300 No Warning - With Rescue 41,800 29,400 16,200 With Warning - With Rescue 32,600 19,200 11,400 Aiming P o i n t ftf _2 - Chosen t o Give Maximum E f f e c t on One Grouping of V i t a l P o i n t s5 No Warning - No Rescue 29,300 11,300 8,100 No Warning - With Rescue 14,500 16,400 10,700 With Warning - With Rescue 10,700 11,300 8,500 No Warning - No Rescue 70,700 17,400 10,700 No Warning - With Rescue 35,500 30,000 16,800 With Warning - With Rescue 26,200 19,000 11,200 oints Aiming P o i n t jr _3 - Chosen t o Give Maximum E f f e c t on a Second Grouping of V i t a l P"UJLtiUti 11,300 6,800 4,900 No Warning - No Rescue 38,900 12, 900 9,600 No Warning - With Rescue 4,500 9,200 6,100 No Warning - With Rescue 15,900 21,300 13,500 With Warning - With Rescue 2,700 6,300 4,700 With Warning - V/ith Rescue 10,700 13,300 6*600 No Warning - No Rescue 000127 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information IABIE II - CASUALTIES AS PERCENTAGE OF POHJIATION x TOP SECRET DAYTIME ATTACK ,30 Kiloton Bomb CAN/ffllAN EYES ONIY 100 K i l o t o n Bomb Aiming Point # I-D - Chosen to Give Maximum Effect on Daytime Distribution of P Population opulation Killed Seriously Injured Lightly Injured No Warning - No Rescue 30 10 5 No Warning - With Rescue 20 10 With Warning - With Rescue 15 10 Lightly Injured Killed Seriously Injured No Warning - No Reacu6 50 10 5 5 No Warning - With Rescue 30 20 10 5 With Warning - With Rescue 25 10 5 No Wariiiuft - No Rescue 50 10 5 No Warning - With Rescue 30 20 10 With Warning - With Rescue 20 10 10 Aiming Point j 2 - Chosen to Give Maxi.uu.ii Effect on One Grouping of Vital Points No Warning - No Resoue 25 10 5 No Warning - With Rescue 10 15 10 With Warning - With Rescue 10 10 5 Aiming P o i n t ^ 3 - Chosen t o Give Maximum E f f e c t on a Second Grouping of V i t a l P o i n t s No Warning - No Rescue 5 5 5 No Warning - No Rescue 20 10 5 No Warning - With Rescue 5 5 5 No Warning - With Rescue 10 10 10 Jp 5 5 With Warning - With Rescue 5 10 5 With Warning - With Rescue x Based on 172,000 - w i t h i n 5 m i l e r a d i u s .

They have been adapted for the present study by raising those points which are important to the Joint Canadian U.S, war effort from Category "A" to a superior Category "AAM, and by restating the significance of the categories. The categories used are as follows: Categories "AA" Individual plants or buildings of sufficient impoi*tance to the North American war effort to be considered possible atomic bomb targets, irrespective of any effects of an A-bomb attack on the target on other Vital Points, Additional effects will, however, play a part in determining the relative importance of Category "AA" targets and they have, therefore, been studied and reported. Category "A" Individual plants or buildings not of sufficient importance to the North American war effort to be considered A-bomb targets by themselves, but which may become A-bomb targets if the other effects of the explosion of a bomb over the target would produce a sufficient cumulative effect on population and other Vital Points. Category "B" Important points to be considered in conjunction with attacks on Category "AA" targets. Category "C" Minor points to be considered in conjunction with attacks on Category "AA" and Category "A" targets. 000138 � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
