when i was in the air force i worked around 35 million watts of microwave space radar for two and a half years. i got out after that and slept for like 6 months straight. it was radiation sickness, i am sure. it also didnt help my thyroid, i am double sure.
if your buddy had been taking Iodine and boron at the time he probably would not be on meds.
anything is possible. he could make a full recovery with glandulars and Iodine and companions.
