Function attenuated_intensity 

pub fn attenuated_intensity(
    initial_intensity: f64,
    linear_attenuation_coefficient: f64,
    thickness: f64,
) -> Option<f64>

Computes attenuated intensity with I = I0 * e^(-mu * x).

Examples

use use_radiation::attenuated_intensity;

let Some(value) = attenuated_intensity(100.0, core::f64::consts::LN_2, 1.0) else {
    panic!("expected attenuated intensity");
};

assert!((value - 50.0).abs() < 1.0e-12);
