Abstract
A method for treating a cancerous tumor, by implanting in the cancerous tumor at least one diffusing alpha-emitter radiation therapy (DaRT) source (21) with a suitable radon release rate and for a given duration, such that the source (21) provides during the given duration a cumulated activity of released radon of at least 10 Mega becquerel (MBq) hour, per centimeter length. Optionally, the sources (21) are implanted in an array (160) of sources (21), each source separated from its neighboring sources (21) in the array by not more than 4.5 millimeters.
