Hello All researchers of Health/Medical/Radiation Physics, at what Dose Rate of Co-60 teletherapy source should be replaced? I have searched but find NAND!
Is any IAEA, AAPM guidelines/recommendations available?
Co-60 teletherapy source,
Is any IAEA, AAPM guidelines/recommendations available?
Output up to 50 cGy/min. at Normal treatment distance (NTD=80 cm.) for 10 x 10 cm. x cm. should used.
The note: for Co-60 tele therapy sources in external radiotherapy , the maximum dose rate don't should lower than 70 cGy/min ( in SSD=100 cm & 10 x 10 cm. x cm. field size ).
excuse me. The note: for Co-60 tele therapy sources in external radiotherapy , the minimum dose rate don't should lower than 70 cGy/min ( in SSD=100 cm & 10 x 10 cm. x cm. field size ).
Yes, minimum dose rate 50 cGy/min at SSD=80 cm for Field size= 10 X 10 cm x cm is acceptable for external beam radiotherapy. Because below this dose rate the treatment reproducibility will decreased and treatment outcomes will be affected.
Thanks to all
Is there any IAEA, AAPM or other guidelines/recommendations available in this regard?
