Exposure Formula:
From: | To: |
Gamma radiation exposure is the total amount of radiation absorbed over a period of time. It is calculated by multiplying the dose rate (radiation per unit time) by the duration of exposure.
The calculator uses the exposure formula:
Where:
Explanation: The equation calculates total exposure by multiplying the radiation intensity by the exposure duration.
Details: Accurate exposure calculation is crucial for radiation safety, determining protective measures, and assessing health risks from gamma radiation.
Tips: Enter dose rate in units/hour and time in hours. All values must be valid (dose rate > 0, time > 0).
Q1: What units should I use for dose rate?
A: The calculator uses generic "units/hour". For specific applications, use appropriate units like mSv/hour or Gy/hour.
Q2: What are safe exposure limits?
A: Limits vary by jurisdiction and situation. Occupational limits are typically 50 mSv/year, with public limits much lower.
Q3: Does this account for distance from source?
A: No, the dose rate should already account for distance (inverse square law) before being entered into this calculator.
Q4: Can this be used for other radiation types?
A: The basic calculation applies, but different radiation types have different biological effectiveness factors.
Q5: How does intermittent exposure affect the calculation?
A: For intermittent exposure, calculate each segment separately and sum the exposures.
