Body surface dosimetry following re-injection of 111In-leucocytes.
The dose to a young infant cared for by a parent re-injected with 111In-leucocytes was estimated from the exposure of thermoluminescent dosimeters at five sites on the chest wall of eight patients. The UK Guidance Notes recommend that patients with a residual activity exceeding 20 MBq of 111In should avoid non-essential contact with children. The results confirmed those of an earlier preliminary study which showed that re-injection of 20 MBq of 111In-leucocytes to a parent could lead to a close contact dose greater than 1 mSv. It was concluded that the 111In-leucocyte activity administered to a parent of a young infant should not exceed 10 MBq.
