Being IN charge of secondary standard dosimetry laboratory and trying to establish luminescent dosimetry laboratory for start of remote audit services to cancer hospitals of Pakistan. I am trying to purchase the RISO/TL-OSL reader DA-20. For calibration of our dosimeters, we have a huge range of irradiation facility (alpha, Beta and gamma standard radiation sources). I don't want to purchase the 90 Sr/Y beta source along with this system. Is it necessary to purchase this beta source ( 90 Sr/Y ) for start and operation of RISO reader system?
Dear Sir.
it is not necessary to have the beta source of the RISO reader however it is practical to use it in order to characterize your detectors (sensitivity, reproducibility, homogeneity, ...). I advise you to buy it it will help you a lot for the TLD. because with this source you can be independent of the calibration installations.
CORDIALLY
I Think, Beta irradiator should be purchased as, without an irradiator, working efficiency will get disturbed. Furthermore, the granular size measurement will become difficult.
