The value for a resistant strain of bacterial spores is 0.7 kGy when radiation sterilised. Usually, a 60 Co source delivers a 25 kGy dose in 13 minutes and is used to sterilise syringes where the typical contamination level is 100 bacteria per syringe. The radiation sources shielding was reactivated early which reduced the exposure time from 13 minutes to just 45 seconds. How many viable bacteria will remain on the syringes (or syringes per bacteria)? Give your answer as a whole number with unit description to demonstrate your understanding of the calculation.
