Abstract
Many entomological problems require the identification and observation of insects without disturbing their surroundings. Such problems are usually concerned with insects within host or pupal coverings and radiography is a method well suited to their solution. The technique is a special type of radiography in which soft X-rays (wave length longer than about 0.25A), passing through an object of low density, produce a shadow image on fine-grain film in contact with the object.Keywords
