3. A tower shot. Ground dirt rises along the stem, but very little actually mixes with the fireball.

4. An air shot—3,500 feet above ground. No dirt.
5. Leg bone of a three-month-old rabbit killed ten minutes after injection of Sr⁸⁹. The darkened areas show where the strontium has been deposited. Sr⁹⁰ and normal Sr⁸⁸ would be deposited in the same places. It is an important fact that the deposition is fairly uniform in the calcified portions of the bone.
