1. For irradiations of the chest wall, dose distribution calculations by means of pencil beam algorithm may be applied.

2. The irradiations were carried out at Bremsstrahlungs produced by electron accelerator Microtron MT-25 of the Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research, Dubna, Russia

3. Sidual Anhematopoiesis and delayed genotoxic ef fects) caused by exposure to a high challenge dose from low-LET (X-ray) or high-LET (carbon and neon ion) irradiations
